I've been taking 5 HTP for a while as I do not want to take an SSRI because of side effects. It always seemed to help stabilize my mood but I am now wondering if it could be the primary cause of severe sinus pressure in the upper bridge of my nose and face while also giving me daily headaches. I've stopped taking it but it could if it is the cause, it could take a while to exit my system. I question this because I've been to many doctors about this headache problem and am now going to see a Neurologist. Went to 2 ENT docs, one said it could be infection and another said he thought it was migraines. This is what got me thinking it could be related to 5 HTP. Not a lot of information on this because people think 5 HTP should help with migraines. I realize everyone's make up is different but hoping for some feedback. I've decided to stop taking medications all together for the time being to see if I can get to the bottom of this problem as it is really debilitating and no need to over medicate. However, if anyone has experienced this I'd love to hear, while also wondering how long it took for headaches to subside once quitting this supplement. Tired of always having a cloudy head! Thanks in advance!
