So last year in June, upto July I had myriad symptoms,ranging from twitching muscles, headaches, body pain, dizziness, extreme fatigue, weakness. The good news is that except the occasional twitch, that's all gone now, and I have since resumed life as usual. I literally had cycles where I worried about MS, then ALS, and every other serious disease I could somewhat attribute my symptoms to. I had 3 ER visits and multiple consultations and tests, all normal, except a very low vitamin D, which I have since gotten to the normal level through injections, sun exposure and oral vitamin D supplements. They never really figured out what was wrong, and I was diagnosed with anxiety. I resolved to stay away from Google for health purposes and WebMD, and it did me a huge favor. So what I'm trying to say is, even though the symptoms were very real for me, and the fear was there, there was nothing to worry about. For part 2 of the story, please read on. A few days back, I started experiencing a constriction in my throat, so I immediately saw my doctor about it. She said my lymph is swollen, no big deal, so might have a mild infection, and prescribed Allegra. Now, I have been taking it for 5 days, it's not gone down in size, in fact it has gotten slightly bigger. I'm going to see her again this morning, but I slowly find myself slipping back into the panic. The panic is worse because it's not accompanied by a cold or anything. Also I have massive hair fall, but my thyroid test from July was normal (when I started having it). Has anybody had experience with this kind of thing before?
