whatispain- i have had bouts with sciatica and i know it is painful ! my first treatment with pain mgmt for it back in 2005, the dr used a fluoroscope to do an injection diretly into hip socket - PAIN GONE IMMEDIATELY, and i did not have any sciatica flare ups for more than a year & so far, have not had to have another hip socket injection! he gave me a morphine lollipop to relax me, once i didnt give a crap, he began the procedure which was very quick. he gave me a local anesthetic injection to nurab the area of hip injection. all i felt was a tiny prick. after a few minutes he was sticking the area to make sure i had no feeling there- i didnt feel any of the pricks. knowing it was nice and deadened, he did the hip socket injection- i never felt a thing and he was done very quickly.
sounRAB like the first injection you had, the dr did not use the fluoroscope (xray guidance machine) that shows them exactly where they need to send the needle. NEVER let a dr give you an injection in your spine without using the fluoroscope !
i suggest you ask dr to do a hip socket injection, as the sciatic nerve goes dead thru it and causes pain all the way down to your ankle. another thing, maybe you should have a nerve conduction study done. i had one done in early 2010 on both legs from knee to ankle, and it showed severe nerve damage in left leg, minor in right leg. my left leg, i felt very few shocks. the dr diagnosed it as peripheral neuropathy, possibly resulting from lower spine damage. i also have pain and nurabness in feet. i have ddd, osteoarthritis, buldging disc, and osteophytes in lower spine, and even worse problems in my cervical spine.
i have had one epidural at c3/4 level with made the pain worse, so no more of those. i now use the LIDODERM patches on my neck, along with oral meRAB & TENS unit. lidoderm helps the most, but since they can only be used for 12 hours out of 24, i rely on meRAB and TENS during awake time. i also wear a neck brace, on 30 minutes off 30 minutes repeat during daytime, but not when i have to drive.
ask dr for lidoderm patches (this contains nurabing agent lidocaine for pain), voltaren gel topical , and or flector patches (contains anti-inflammatory med), all are topical, not addictive or dependency forming, and can be used anywhere on the body (other than the head of course). these are my life line meRAB... good luck to you - hugs
