Hi ! Good morning. I am Dr Shaeef answering your query.
On the diarrhea front, I would advise you to avoid eating from outside if you do to rule out any intestinal infections. If I were your doctor, I would advise you for a routine
stool test for ova and cyst, a routine
blood test like CBC, ESR, Blood sugar, and special blood tests like LFT, HbsAg, HIV, and a
thyroid function tests. If all the tests are normal and non reactive, then I would not hesitate to refer you to a gastroenterologist for an endoscopic evaluation of your gut and a possible tissue biopsy to arrive at a diagnosis. An
ultrasound of abdomen might also prove to be helpful. The lesions in your legs could be due to some allergic manifestation which has responded to the anti
histamine drug taken by you.
I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts.
Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
