I'm sorry to hear of your ongoing problems. I think you are on to something when you said you need to make a change now by choice or later with no choice. It seems pretty clear from your history that you can't tolerate working at a computer all day. If at all possible, I'd try to make another life change now and hope your body responds as well to the rest as it did last time.

I fell into the latter group and was forced to stop working by my symptoms and was never able to return. I finally had surgery because nothing else had helped to that point, except ice and abdominal breathing, and it's hard to make a life lying on the floor. Unfortunately, surgery only made things worse for me.

I hope you can make a change now that will allow you to avoid a lifetime of pain.

Take care,
Kelly
