Started with diarrhoea in a week after surgery. Took tablet for diarrhoea - took immodium 2. Skin rashes after 10 days of surgery 3. Stool impaction after 2 weeks of surgery 4. Incomplete bowel evacuation after stool impaction...still the problem is not solved 4. Developed stomach ulcer in February...feeling something stuck in throat but it's not painful..took panstone40 for 1 month which is suggested by ent specialist.but the problem is still not gone. Still some food is stuck inside throat 5. Now there is a sensation of head swaying for 2 days...head is not spinning but I feel like floating for 2-3 secs then it continues after sometime. I am completely under depression for these problems...I am trying to conceive but cannot because of these issues. Please help me to overcome this problem
