I have had the same problem I suffer with acute sciatic pain down my legs feet and back. I had a micro-discectomy in 1996,and another disc herniated but went back itself but is permanently swollen. The best 2 painkillers I have been given are Solpodol caps 2 and Tramadol 2 together,and every 4 hours continue taking 2 of each maximum 8 a day.

I have tried various painkillers and that seems to work the best,good luck hope it works for you to.

Kind Regards,

Carole

In addition to meds, ask your doctor for a referral to a physical therapist who does myofascial release.  I have gotten a lot of help from this process.  It's difficult to understand.  Somehow, trained and sensitive fingers are able to relieve pressure on nerves and soft tissue by manipulating it.  One of them compared it to "you can't force a sock drawer that is stuffed full ... you have to ease the socks into place so the drawer can shut".  The great thing is there is virtually nothing required from the patient except some minimal and not painful stretching, and learning some posture tips.  I also got a lazy susan kind of cushion for my car, and you would be surprised how much that little bit of assistance has helped stabilize my spine and hips.  There is also a device called Sacrowedgy that I have used.  (Just search the web and you will find it.) It elevates the pelvic area and forces the hip muscles to relax, taking pressure off the nerve.   I also had the same physical therapist do some dry needling to release knotted muscles that massage and release could not unlock.  This is not licensed in all states.  Hope you get some relief ... sciatica has to be addressed in part as a mechanical thing, not just having pain meds to lower your perception. 

I have the same problem. I have been to the doctors about 5 times in the last 3 month . the best pain relief I have taken is Boots own make Paracetomol & Codeine Extra . Drop 2 in a half glass of water . Lasts about 4 hours . £4.95 for 32 tablets . Hope they work for you.
