Hello. I live in atlanta and have been having chronic headaches over the past month, some sweating and then chills! I am a 51 female who just went off birth control (trilegest) after 10 years (with two breaks for foot surgery 7 years ago and just feeling like a needed a break a little over 3 years ago.) FYI: I am in a monogomous relationship. I was on trilegest and went off ~28 days ago. I also have lumbar scoliosis- so I get massages, acupuncture, and chiropractic care to keep my scoliosis from getting worse (it improved 3.5 degrees over 10 months - as of april). I did more traveling (flying, conferences and dinners) in June -and felt very compressed after that phase. My first debilitating headache (it got progessively worse when I was traveling, was June 22. Probably have had 10 since then, with three in the three nights. I swim, but now our gym pool is down, so I am not swimming too much - unless I drive 20 miles round trip to a sister gym with a pool - but am finding that the head right now is knocking me out. I do hot tubs and baths to ease muscle aches. I live in atlanta which is going through an awful hot spell. I am seeing my primary care guy monday am at 8:20 am, My temperature after my massage today was 100.69 degrees, My forward did not feel hot, but my massage therapist mentioned he noticed my body felt hot. I went through something similar last summer, without the headaces (two weeks of feeling zapped from the heat). So, my primary concern is the headaches. Thinking this could be: estrogen withdrawal, menopause ( I had a night sweat two nights ago), or heat exhaustion or dehydration. I also purchased an inversion table. I have only used it at 30 degrees, but have stopped since sunday to try to control factors. For a while I was wearing a neck brace to remind myself to keep my chin up when working, but have stopped that as well. Any thoughts on what else I should consider? Thanks, Susan Hogan
