i had a glycerol injection 4 weeks ago. I am still having pain, in some respects a bit sharper then prior to the procedure. Dr. Lim ant John Hopkins performed the procedure. After complaining of the pain, they put me on a high dos of steriods, which have helped. But pain is still there. Wondering if anyone else has had this and how long it took to feel relief,if any at all. The thought process is that the nerve needs to calm down. I would love to hear other experiences, because I have bilteral TN and will have to undergo a MVD on the other side. Looking forward to hearing any feedback. thanks ai
