Drug rashes are generally defined as the reaction of the body to certain kinds of diseases. Different drugs result in different kinds of diseases which sometimes are as dangerous as being life-threatening. There are different types of drug rashes. They can manifest in different forms. Common ones are:

1. Blisters and swelling: Many drugs result in acute blisters and swelling in different parts of the body. This condition, if unchecked, may aggravate, leading to dangerous consequences.
2. Prolonged high fever: Continuous rise in fever is often diagnosed as a serious consequence of certain drugs.
3. Abnormal redness of the skin: Few medicines often result in sudden reddening of the skin. This condition continues till the drug is discontinued.
4. Rash and itching: This is considered as one of the most common side-effects of medicines. Often medicines result in continuous itching and rashes on the skin that also causes swelling, if unchecked.
5. Swelling of tissues: Tissues often swell up as a result of consumption of certain medicines. Consequently, the concerned person experiences problems in breathing and often a drastic fall in blood pressure.

However, there are ways that one can adopt in order to combat drug rashes.

1. Identify and discontinue the drug: One of the most essential ways of combating drug rashes is to identify the drug and immediately discontinue its consumption.
2. Avoid using chemicals: One way of easy recuperation is to avoid using chemicals, soaps on the affected areas. If continued to use, they aggravate the already caused damage. On the other hand, Calamine can be used for treating drugs.
3. Wear loose-fitting clothes: Wearing tight clothes that sticks to the body further damages the skin. Instead, one should try to wear loose-fitted clothes that allow the skin to heal.
4. Apply cool compresses: Taking cool showers or applying cool compresses over the affected areas significantly help to recuperate fast.

Folliculitis is an ordinary dermatological condition which causes inflammation of hair follicles of the skin. This condition, which occurs due to both bacterial and fungal infections, causes small red or white pimples to form around the hair follicles. The infection, if left untreated, can spread and turn into rough, coarse sores which may take a long time to heal.

The Staphylococcus aureus bacteria is responsible for causing the infection, which leads to this commonly occurring condition. In some cases, folliculitis can be also caused by viruses and fungi which had perhaps penetrated the ingrown hairs causing subsequent inflammation. This condition is categorized and diagnosed as a superficial or deep infection depending on the amount of hair follicles involved.

Causes:

• Friction caused by shaving or tight - fitting clothes
• Heat and sweat, due to prolonged exposure to the sun
• Skin conditions like acne
• Tightly wrapped bandages or dressings on the skin

Symptoms:

• Clusters of tiny red or white bumps in and around the hair follicles
• Reddened and inflamed skin
• Itchy skin and rashes
• Pus-filled blisters that may crust and later break
• Swelling on the skin

Risk Factors:

Anyone, whether young or old, may develop folliculitis. But, there are certain factors that increase the risks of the condition. The following are some of them:

• Conditions like HIV or AIDS that reduces the immunity in your body
• A pre-existing condition of acne or dermatitis
• Being obese
• Medications and ointments with side effects
• Improper shaving

Many a times, people ignore this condition, presuming that it will heal with time. But if left untreated, complications such as large itchy patches of skin, increased swelling and heightened inflammation of hair follicles may occur.

A head louse is an insect that lives on the human scalp and feeds on human blood. The female louse lays eggs in the head and makes sure the eggs are attached to the hair shaft. It takes around eight days for the egg to hatch. The louse takes another 11 days to mature into an adult louse.

Causes:
The primary cause of head louse is poor personal hygiene. Other causes due to which a person can be infected by lice are:

1. Using combs and towels that are infested.
2. Coming in contact with another person who has this condition.
3. Sharing the bed with a person who is affected by lice.

Symptoms:

When a person is affected by this condition then the following symptoms are observed:

1. The saliva of the lice causes an allergic reaction in the scalp which leads to constant itching. It can occur in various places such as ears, scalp and the neck. It may not occur initially, but it tends to occur after a few weeks.
2. Constant scratching can lead to formation of small red bumps on the skin. A bacterial infection usually occurs from constant itching.
3. It may lead to symptoms of dandruff in the scalp.
4. Presence of various insects in the scalp.

Prevention of Lice:

Lice can be prevented by using medicated shampoos and conditioners to wash the hair. The shampoos are usually based on a chemical called pyrethrin. This compound is toxic for lice and helps in getting rid of it.

You can also opt for the following lifestyle changes to prevent lice:

1. You should avoid sharing your hairbrush with others.
2. In case you have long hair, tie it in buns or ponytails.
3. Add tea tree oil to your shampoo before using it.
4. Keep the scalp clean to prevent infestations.
5. Avoid sharing pillows and clothes.

Pityriasis Rosea is a common skin problem which causes a rash. Although, it can occur at any age, it is most often seen in those between the age  of 10 to 35. It is usually harmless and a pretty common condition. It is also worth noting that Pityriasis Rosea does not spread from person to person.

Causes: The exact cause of Pityriasis Rosea has not been identified yet. Some doctors claim that it is caused by a virus, bacteria, or fungus while others claim that it is caused by an allergic reaction.

Symptoms: There are a fair number of warning signs of the Pityriasis Rosea rash. The symptoms may differ depending on the patient's general health condition, the climate condition, and the season.

1. Size and appearance at first: When the rash first appears, it has a raised border. Basically, it is a pink patch which can be single, round, or oval in shape. 2 cm to 10 cm is the usual range when it comes to the size of the patch.
2. Few days or weeks later: After a few days, 1cm to 2cm patches appear on the abdomen, back, chest, legs and arms area. They sometimes spread to the neck, but rarely to the face.
3. Back patches: The patches on the back are slightly different from the rest. They tend to be angled and look somewhat like a Christmas tree. Sometimes it is itchy, but it goes away within 6 to 8 weeks.

Treatment: Pityriasis Rosea goes away without treatment. It usually lasts about 6 to 8 weeks. However, in order to relieve itching at home:

1. Apply anti-allergic powder.
2. Avoid taking hot showers. Keep the water as cool as possible while taking the bath.
3. Eat a lot of oatmeal and try bath products which have oatmeal in them.
4. Hydrocortisone cream is very good for the itchy areas on your body. However, do not use these on the face or pubic areas.
5. Use antihistamines, but, for children, you must check with the doctor first.
6. Apply moisturizer regularly.
7. Use gentle soaps and avoid deodorant soaps as these worsen the rash and the itching.

A boil or a skin abscess is a type of bacterial skin infection that leads to formation of a pus-filled red bump on the skin. It usually starts in an oil gland or a hair follicle on the face, the armpits, the neck or the shoulders. If a cluster of boils appears, it is called a carbuncle and this is a more severe infection than a boil. However, most boils are caused by minor infection and can be healed with simple treatment at home. Listed below are the various ways to deal with a boil:

1. Boils are not entirely preventable but normal daily hygiene can reduce the frequency of the occurrence of boils.
2. When you notice a boil formation, you should apply a hot compress on it. The heat helps to prevent the formation of too much pus by helping it drain faster. When the blood circulation to the area is improved by the heat, the antibodies help to draw out the germs.
3. The boil usually drains on its own. You may try draining it yourself but only when it is soft. Poking a hard boil can be extremely painful; it may bleed and make the infection worse. It is usually best to let it drain by itself.
4. When the boil starts draining, you can clean the infected area with an antibacterial soap daily till the boil is drained and flattened. You may clean it with some rubbing alcohol in order to prevent the germs in the pus from spreading to other areas of the body.
5. The infected area can be kept covered with sterile gauze coated with antibiotic ointment.
6. Penicillin-based antibiotics can be used to treat the boil but only if it is a severe infection. 
7. 7. If the boil is excessively painful, you can use pain relievers such as ibuprofen or paracetamol.
8. Avoid sitting in one particular position for too long because this increases the pain.
9. It is important to wash your hands every time you touch the draining boil because the bacteria is extremely contagious and can spread to other areas of your skin as well as to other people.
10. All the articles which have been used to treat the boils like the gauze, cloth, cotton and hot compress should either be discarded or disinfected to avoid spreading of the infection.
