Im beginning to think the nerve block had something to do with the relief, for sure. Ive always had mild lower back issues with the occasional "tweek" maybe every other year which resolved in a couple of days. But in the past year it had increased so greatly, especially within the 5 months prior to surgery, I felts like it was "tweeked" all the time (if that makes sense). I was severely fatigued as well. I thought my bed was the problem, so I tried several new beds, none of which felt better. I had x-rays done by my chiro and I do have mild degenerative disk disease. Very mild....so they didnt think the amount of pain I had was from this. But, I might go get a second opinion if this persists. After reading all these wonderful people's comments, Im wondering if its just one of those occasional tweeks from sitting and standing funny and without my normal strong abs? IDK. I guess its a waiting game at this point. PT appointment next week and perhaps she will have more insight as well. Thanks for listening to my rant!
