I was suffering from fever and abdominal pain due to gastric one month ago. I checked and took medicine and was ok. After 2 weeks I feel muscle pain and heart palpitations along with high blood pressure almost 142/88. I'm consulting general physician also and running with medication. Sometimes I feel heart palpitations with discomfort and much more fatigue. Weakness improved a little but still im not able do heavy work or got tired after walking for 15-20 minutes. Also feel muscle pain mainly in leg and back sometimes. What should I do. I got panic when heart palpitations occur. My physician told me that its only due to the weakness. Last 3 -4days I was feeling much better. The day before yesterday I did some exercise and run and I got pain on my body at evening. Then at night I was watching tv till 11: 30 and was feeling like discomfort. Then I tried to sleep and found my heart is beating faster along with discomfort and was not able to sleep almost for 1and 1/2 hrs. I have done a blood test of blood cells and it was ok. What should I do to have the better results!
