If you have herniation of L4-L5-& S1 I recommend ILIF spinal fusion. I had my L4-L5 done in Dec. and it was worth it, however I also recommend getting the S1 taken care of at the same time. I am 2 1/2 months post-op and now need L5-S1 fusion surgery due to severe sciatica. You’ve already gone the route of epidurals and after 4 maybe its time to have the ILIF. I was up walking on my own the very next day and even though I have to have more surgery I really recommend it for long term relief. Any type of exercise will just aggravate the disc. I tried swimming as it was no impact and had to even stop it due to the twisting. Good luck to you.
What are the risks and side effects?
Generally speaking, transforaminal injections are is safe. However, with any procedure there are risks, side effects and possibility of complications. The most common side effect is pain from the actual injection once the local anesthetic wears off and this pain is temporary. The other uncommon risk involve spinal puncture with headaches, infection, bleeding inside the epidural space, nerve damage and worsening of symptoms. Other uncommon risks are related to the side effects of the long acting steroid such as weight gain, increase in blood sugar in diabetics, water retention and suppression of body's own natural production of steroids.
