Hi, i have severe headache in complete forehead area. It occurs 5 out of 7 days. The pain is very acute on most of the days and doesnt subside easily. Previously taken medications were ciplar and sibelium which worked well for few months but later stopped affecting. Then took sensival and divalproex which didnot suit and caused extreme nausea and constipation. Not taking any treatment rite now.head ache occurs because of disturbed sleep, exertion, some times exhaustive work. Please advise. The problem ia around 20 years old.
