Blueslfb... Sounds like you're pretty sure it's your disc, but just for the record, if you've been taking cholesterol medicine, any statin based drug, for a long time, it can cause you to suddenly lose your strength. This is one of the known, but rarely emphasized, statin side effects and is why I ended up shooting 19# instead of 52#. I've spent the last year working back up to 32#. So, if you've been taking statins for a long time, notify your doctor if you feel you're losing strength. I ended up telling my doctor if it was a choice between being that weak or rising a stroke, I'd take the stroke. This led to his ordering an ultra sound test of the carotid artery, which showed that while I have a high "free" cholesterol in my blood, none of it is sticking to my arteries, which are as good as a teenagers! I never needed the Lipitor in the first place. If this info helps you or anyone, it was worth posting....
