Hi. I'm a 32 year old female and for the past 8 months or so I have been experiencing widespread muscle twitching (painless), as well as a shaky feeling, inner buzzing sometimes in my hand and foot (*seems* to be mainly my left side; I'm right-handed), and a jerky feeling when I move my muscles (pretty much all muscles have this reaction, mainly if I'm exerting effort with them, like pulling pants on, resisting gravity, etc. Not from the action of simply standing up, though.) None of this is really externally visible; I just feel it on the inside (24/7; it never relents. Even when I'm just waking up I feel it.) I've seen a neurologist, gastroenterologist, cardiologist, lyme specialist, and had autoimmune testing as well as a brain MRI to rule out MS. In the beginning I also had extreme dizziness and thought I saw flashing lights at times (I had one migraine without pain, just a flashing light in my left eye, which I had once a few years ago as well.) I still sometimes have heart palpitations. All doctors so far have told me this is anxiety; they can't find anything physically wrong. I'm afraid someone has missed something. Any advice? I hope this is just anxiety. I *have* been through a lot emotionally over the last 10 years dealing with an ill parent who finally passed away 2 years ago. I am sleeping well, eating well (I try to limit processed foods, and I try to limit caffeine though I am still drinking it). No family history of anything sinister that I'm aware of except for unidentified neurological condition suffered by an uncle who passed away several years back at a young age. Thank you; sorry for being verbose, just didn't want to miss anything that may be pertinent.
