HI. I am suffering with rashes on my skin of left buttock and it is too itchy in the every night. I hope it is kind of skin allergy. Whenever I scratch it is painting and burning sensation. After scratching those rashes I will lose skin and affected part will get dry again after someday same thing will happen as above. I cannot go to doctor and show that place. Hope will understand my problem. I request to anyone can suggest me with a good ointment or medicine to get cure.
