You're stressing about the big " what if". I have gone through this scenario with someone else on communitys so here goes. 30,000 people have ALS in the US and 1500 diagnosed annually. The vast majority of those are knocked off by neuros while walking in the room ( this isn't my opinion, its fact, ask a neuro or google if you doubt it). Lets exaggerate and say 50% of als people sneak buy the physical exam and demand an EMG( which is far from reality). Now lets say, because they are a little harder to sneak past( like extremely hard) exaggerating again at 20%. Your at 150 people a year( it's probably more like 20 people but lets just say) .Now, there are 307 million people in the US( give or take a few) so your odds are 1:204,600,000 that this is you, even with our gross exaggerations. Now, 11,000,000 - 18,000,000 people have or have had at some time a conversion disorder(stress related symptom type illness), 300,000 - 400,000 have MS, 15,000,000 have Fibromyalgia and a whopping 20-30 million have anxiety severe enough to affect their everyday lives and cause physical symptoms ( watch TV ads for SSRI's, they wouldn't advertise if there was no market). So, how close is that "what if" looking now. I know it's hard to rationalize when dealing with fear and anxiety but dude come on. You are wasting time worrying about something that your about as likely to have as I am winning the lottery....…Twice! Rejoice man, you're okay.
