Holy Headache batman!! What gives?!

I'm 2 months post op and doing great! Had a few issues with dehydration, and dropping blood pressure about a month out, but all is good now but my head! I wonder if its hormones or what?! I have had a headache from hell since last Friday...going to my PCM tomorrow but not even Tylenol is touching it...nothing not my topamax that I take for migraine prevention...Suggestions please! 

How are you doing with your water? Dehydration can cause bad headaches too. The first couple of weeks I couldn't get enough water in and I started getting a headache. Also how is your blood pressure?

my bp is perfect now thank goodness! I check it daily a few times because the last time it dropped so did I! Right on my face into the wall and was out like a light, ended up with a ride by ambulance to the ER. I get about 2 1/2 to 3 liters of water in a day..all I do is drink it seems, because I was having a lot of dehydration issues as well...

I forgot to mention now that I have been losing weight I also get real bad migranes around the time of my period. Maybe a little bit of caffiene will help. Try maybe a pamprin it has caffiene in it. Just a suggestion???Not sure if it will work
