I had several back and spine issues nothing worked except an epidural steroid injection and my pain disappear completely, not only that, my overall health improved , I had a boost of energy and strentgh, and also I was able to exercise more Intensively, I really loved it, My question is how true is it, this type of injection can cause permanent paralysis and brain damage in the long run? is it because of the type of steroid they use? what's yur knowledge about it guys? thank you.
