Hi all - I'm posting for the usual reasons, but wanted to first say thank you - much of the commentary here has been extremely helpful even prior to actually being registered and able to post.I have a reoccurring lower back issue with my L5 or L$ disc, which most recently produced fairly regular tingling, tightness and numbness in my left leg. My father also passed away from MS after a 31 year battle with it, so I always have that in the back of my mind. Anyway, about 5 weeks ago, I started to feel numbness and tingling in my right leg as well as my left and basically panicked, thinking it was maybe the start of MS. I started on a litany of MD visits, psychologist visits, physical therapy and now two neurologist appointments. Thankfully, I keep getting a clean bill of health (though my neuro has now requested a brain MRI to try and further reassure me). Along the way, my numbness and tingling seemed to morph into nearly constant muscle twitches in my lower legs, then feet, and now also occasionally upper legs, shoulders, arms and fingers. At my last neuro visit he was able to see the twitching in one of my legs but still is absolutely convinced that it's nothing dire. Frankly, before finding this site I was starting to think that my extreme anxiety had almost sent my body into arrest / spasm (I've had trouble sleeping without sleeping pills for like two weeks now).Sound familiar to anyone?? I still am not quite sure why he's so sure it's not MS, unfortunately, though I know soundly believe that I don't have ALS thankfully. I also have occasional pain in joints and a fatigued feeling in my legs, especially in the morning, but for the most part the main symptom I have is twitches and a light "crawling" feeling in my calves and feet.This is a great site and you all are a great support for each other! Thanks for any replies or thoughts.
