I Have Started Sweating Profusely, Mostly Head And Neck ,

I have started sweating profusely, mostly head and neck , when I am laying down. It doesn't only occur at night. I have been taking estrogen for 4years due to hysterectomy and have had regular check of hormone levels. It does not feel like that sweating. I have been having bouts with high BP and meds ,total, were increased to 50mg about a week or so ago. Sweating has continued. I was diagnosed with Graves disease about 4yrs ago but have been off meds for about 3years.
