I last posted in 2012 towards the end of the year. I had been having multiple deficiencies (thyroid, cortisol) and had somewhat "recovered" from many symptoms (tiredness, muscles twitching) except for my arm muscles that were still weak at the time (for over a year). THen in December 2012, I had a complete recovery. I felt really well until December 2014. Now I'm having neuro issues again. Left leg started tingling and then went heavy. Left arm is crampy and I'm really exhausted. This happened while I was on an antibiotic. I think it is a bit strange. But of course, I am still worried about MS because a few years ago I had an MRI and the two lesions were "atypical" of MS. Anyone have any idea what can be wrong? THis is very similar to the 2011/12 episode but this time NO deficiencies are showing up.
