can do a lot of damage. You can end up having to use more meds with less effect, damaging organs like stomch, liver, kidneys and even messing with your brain function. You hang in there. I hurt my back again, fortunatly did not do any more damage to the disk. You may want to ak about a TENS unit if the pain continues for weeks or gets worse again.. I love mine and use it when needed. You hang in there and don't hesitate to talk with me for morale and/or support.
