I have not had a lumbar block done so can't speak to that personally. People post varying degrees of discomfort. I am sure operator skill and individual response really drive that. I hope it brings you more relief.

Avoiding surgery when you can is always a good thing. hopefully your issues will get resolved way before that point. If your injection was not tendon sheath specific it may be worth another look before signing up for anything really invasive.

A lot of us have really benefited from being in the pool. It is a great way to keep up exercise and circulation without so much stress on the limb. That and the water is just a pleasant place to be. Gotta build in some fun and relaxation with all this recovery business!

take care and post after your block is done. Some people get really good results. I am sending warm wishes for you to be one of them.
