Im 35 years old. Last 10- 15 days im feeling little pain in back side of my head to middle portion. There is no double vision im facing. There is no specific time its happening. I have gas problem. Please advise me. Im scared abt that. Yes one medicine Dr. Could not identify the reason but told me two of my tonsil gland badly enlarge. That may be also cause for that. Pressure was normal. I did some exercise like push up .belly crunch etc. Not wet exercise.
