headaches????

 I am 13 months out and the last 2 weeks Ive been having headaches.  Feels like a too much caffeine headache...but I dont drink ANY caffeine.  Today is the first time I checked my pb, it was 100/66.  Maybe its low and thats causing the headaches?  Dont know...any ideas?????

Maybe it's the opposite--low bp causing headaches.  I've had headaches daily for over 15 years.  I can't blame these headaches on my RNY though, as the RNY was 5 1/2 years ago.  I've taken Vicodin and began alternating with Norco twice daily until recently.  It's legal in my state to used medical marijuana. I know this is a "touchy situation", but I did get my medical card and have begun to try a topical cannabis cream, which seems to alleve the headaches around 80%.  At the same time, I've bagan to dial back the other pain meds. This also seems to resolve constipation issues that I had daily.  This is my personal decision and I'm not advocating it for anyone.  I've also tried some mild cannabis edibles, and this seems to alleviate my insomnia. Although I've taken sleeping pills for 15 years, I began having sleeping issues post op.  Since I began using the edibles, my evening sleep is much better getting almost 7 hours sleep nightly as opposed to 5 hours or less before.

Are you drinking enough water?  Dehydration can lead to low bp and headaches...

Ditto: "Are you drinking enough water? Dehydration can lead to low bp and headaches..."

 Low BP, low blood sugar, dehydration.... common & treatable causes. If you're drinking/eating/sleeping enough and labs are all normal, consider talking to your dr for other causes - may require a referral to a neurologist if it's not caused by something simple.

I personally find cannabis, medical marijuana, very helpful. I use a tincture (oil) at bedtime and vape for breakthrough pain. I have heard from my friends that hemp oil also helps. Just googled to find out the difference and found this cbd vs hemp oil
