hi, I have a rare and complicated disorder which produces neuro symptoms but sadly doesn't show up in a blood test....which is very frustrating. I'm not saying you have this because there are specific symptoms which you don't mention. But there are other sort of related disorders which flag themselves up as possible. I don't think it's anything to do with the marijuana use or even the supplements (though I have a certain sensitivity to certain supplements eg ecinachea (sp) makes me so ill!!!) When we become ill I think we get preoccupied with trying to find a reason for it. Which is normal. We think that there should be a specific reason why we feel so bad. But the truth is our system can malfunction at any time. Often more likely as the result of an everyday type of infection or something like that. It can kick start an autoimmune response and that's very difficult then to diagnose because symptoms are so generalised and difficult to pin down. You can go from one doc to another who simply don't have a clue what's going on because they don't have the specialised knowledge needed to pinpoint what actually is going on. I would like some more info on your symptoms and to suggest what you need to be doing. I'm in the uk though so I am aware the process can be different in different countries. We have a really good free healthcare system which is wonderful and just as well considering I've had to see so many docs in the last 7 or 8 years.
