Hi there. I've been having some problems the last few months. I've been in and out of the emergency room, seen countless doctors, and I'm starting to feel like I'm losing my mind or something. I've had obsessive compulsive disorder my whole life and been dealing with anxiety for a long time. I've tried a few different medications for it, which I stopped because they wern't helping like I'd hoped. I've seen at least 3 different therapists and been to a group for ocd. Nothing seemed to help until I tried marijuana with a friend a couple years back.
So I got addicted to it.

About two years into smoking I started getting slight chest discomfort in the left side of my chest with head pressure that would seem to build up in my ears and eyes a bit. I kept smoking, thinking nothing of it, until a few months ago, it started getting really bad and very intense. My chest would start feeling really tight, start burning, cramping, tingling and feeling like someone was pushing on my chest. It felt deep in my chest, under the bone. I could feel my heart beating and feel palpatations. I would feel the tingling go down my left arm into my hand and up into my jaw and mouth, as well as down into my feet a bit. I would get stomach cramps as well. One specific time I felt the right side of my face go slightly numb with tingling up my neck into my head.
Since these episodes, I've been having trouble sleeping. I get endless muscle spasms all over my body that seem to tickle more than hurt. My left arm and leg feel like they don't get enough blood and fall asleep(pins and needles) pretty easily it seems. This all makes me very stressed, anxious, and depressed.
I've had at least 4 ekg's. Been put on heart monitors, had a 24 hour take home heart monitor, a CT scan of my head, an mri of my head, an EEG done on my head, blood tests, urine tests. All came back normal. I'm positive the pot wasn't laced because I've tried 3 differen't types from different people, which all yield the same effects on me. I also gave myself an at home drug test that came back negative(except for marijuana

) so I know it was working.
I'm very confused because the doctors have all told me they think it's anxiety but I'm not so sure. I've been dealing with anxiety for my entire life and this has never happened except while on marijuana. I have stopped smoking it, but am still very worried as some of these effects have persisted since I've quit.
Please someone help me. Could this be something serious? I'm in pretty good shape, I don't smoke cigs or drink much. My blood pressure is very good and I've played sports for most of my life.
Thanks,
Derek
