question: Quite suddenly, my lower back and butt hurt, and I thought it was a sciatica issue.  Now my left arm feels as though someone is forcefully pressing his large thumb on my bicep.  ANd my ear oddly aches!  All this today.  What could possibly be the matter?  I am 39 year old female...do not exercise enough but not really overweight.  At home with toddler but I dont carry her a lot.
