Sorry to hear your pathetic condition. Pain in the left side of abdomen radiating to back can be a presenting feature of many disease. It may be due to GERD, gastric or duodenal ulcer
. But as you are in a state to write a mail , I think it's not too severe. Acute intestinal obstuction or pancreatitis may be a possibility but they are more acute and do not allow you to write a mail. However in a background of Tuberculosis
, Subacute intestinal obstruction
may be a possibility.You also mentioned of constipation
which fits with subacute intestinal obstruction. Please go to any government hospital and keep faith on them. Beleive me, without seeing your clinical profile and perfoming some laboratory tests, it's not possible for anyone to give a definite opinion.Keep faith on yourself and the doctor who are treating you. Hope, I answered your queries.
