For the past few months I have a burnt feeling in my tongue as if I have taken a very hot coffee or tea but I have not taken any hot liquid. I have a bitter feeling in my tongue and there is uncomfort feeling in the tongue. I have uneasiness under my right foot (below the finger next to Toe) as something is piercing like a nail/boil under the foot (below the finger next to Toe). I have taken all tests recently viz. CBP, Lipid profile, creatine, LFT and blood sugar. All tests are normal but for fasting blood sugar 126 and triglycerides above normal. I have right inguinal hernia for the past 10 months and I am planning to go for surgery shortly. In the past 8 months my weight decreased by 5 kgs. Any further tests required. Kindly advice.
