So the last week the tingling & shocks in my feet were a little better, however a couple of days ago I started getting this feeling like my legs are conducting electricy from top to bottom. Kind of like when touching your tongue to a 9v battery, except it goes from the top on my legs to the feet and feels deep with-in the tissue. I assume this is myelin loss on my big nerves??? Should i be freaking out? Like i already havent.... But seriously, does this point to a certain diagnosis? I'm not having trouble walking but definately feel weaker from not working out.
