Hello Doctor, My husband had taken 50 to 60 Avil tablets before 10 years. He was taken to the hospital immediatley and recovered after being in coma for 3 days. He was normal for few years. Suddenly he had severe pain in left skull region. When diagnosed through MRI scan it was found the drug as accumulated inside and causes pain. He had an injury in same region when he was a kid. As that area was weaker drug accumulated over there. At the time of diagnosis doctors informed that he could live only for six months. But luckily with continuos treatment he survived. After that he did his Ph.d and married me . Blessed with beautiful kid. But the problem is whenever he gets stressed or angry he gets pain in the same area and pain spreads to left side of the face. We took a scan of brain again and doctors told there is no problem existing. Please advise what shall we do?
