I am 40 yo. Male. I have been having mild (i stress mild) abdominal discomfort on my right side, but also occasionally left and lower abdomen. It is mostly on the left side but it does not have a specific spot: higher lower, sometimes could be on the back, on the front, just under the ribs, etc. and as I said sometimes is on the left side. No history of cancer in my family, but history of IBS and stress related symptoms. I have diabetes, diagnosed less than a year ago (have had tendency to it since a kid - 5.7 and 5.4 where my last A1C readings from 2 days ago and mid March, respectively; 5.7 was the reading that triggered the glucose intolerance test upon which diabetes was confirmed). I'm on 250mg a day of metformin (500mg when I eat more during the weekend). I take enalapril for high blood pressure (which runs in the family). Since starting these medications I have been limiting carbs a lot, eating lots of steamed, boiled vegetables. I have never been eating a lot of meat or fish my whole life. I am a very anxious person and tend to worry about any symptoms. Before feeling this abdominal discomfort I have had symptoms of anxiety attacks (mild chest pain in no specific area, feeling of panic building up, tingling of upper body, arms, etc). Other tests and ECG were negative. The lab work performed 2 days ago showed everything is fine apart from low level of vitamin D (abdominal ECO was negative). My doctor prescribed me vitamin D supplement. Could the abdominal discomfort may be linked to diet and lack of vitamin D. Thanks (sorry for the long posting).
