Dear carmen as you above explained your bad head pain which is migraine
.It can be teated during attack of episode if migraine attack frequency is less or start prophylaxis if it is disturbing your routine life.i suggest you to start amitriptyline
25 mg bed time for 7 days and if you feel better then conitnue it.But if on amitriptyline if you do not get relief then add flunarizine
10 mg od in morning.Continue and keep in follow up.You will live painless life.I tell u another thing that your high BP
during maigraine is due to pain so no need to worry bout your high BP.
