Thank you for the quick reply, Al. I don't know if you saw my other post, but my symptoms seem to have started in my upper arms (my hands seem to be ok) and then went to my legs . . . all in a matter of less than a month. I know I see lots of websites talk about loss of function of limbs and that it usually debilitates one limb before going to the next limb. Is that true too? My symptoms are weakness so I still have full function of all of my limbs, but each and everyone of them has gotten weaker and gotten weaker quickly. Any more input from you or anyone else would be great. Take care and God bless.
