Hey how's it going? I experience alot of the same symptoms as you do. Dizziness, blurry/sensitive vision, slight chest pain, tightness in chest, feeling weak and tired, foggy minded etc. I actually came across a forum on this site where there are TONS of people going through the same thing. You should be able to find it through my profile if you like. Anyways, alot of people contributed their symptoms to anxiety/panic attacks. Another theory that I plan on checking into is "candida overgrowth". There are alot of posts on that forum that explain more about it. It causes many of the symptoms that you just listed, and seems to be easily treatable. It has also been linked to MS, which is interesting since you said you can relate to the symptoms of MS. I'm not a doctor by any means haha, but I think it's worth checking into. I wish you the best of luck and hope things get better for you! Keep us posted!
