Only Ear and stomach pain is from past 4 months But Remaining Symptoms are with me from past 7 Years. I have consulted many doctors but there is no sign of cure. I'm so much worrying about my situation and I have consulted many doctors but there is no sign of cure. Please help me to get rid of my bad health situation. Thank You.
