Hi, been there, seen it done it had the op!
Some people had very good results with physio, there are two main camps of thought and they are compared here:
Williams vs. MckensieI ended up with pain in both legs and a feeling like I'd walked for miles first time every day. I had over 40 months of physio including ultrasound, hydrotherapy, exercises, manipulation, etc. I even had two epidural injections to reduce inflammation as the MRI scans showed small disc bulges at s1-l5, l5-l4 and l4-l3 none of which were (offically) big enough to cause the symptoms! That batch of 3 discs are the most frequent ones to be damaged and are also often damaged through normal wear and tear during life.
I tried a couple of alternative therapies for pain relief, TeNS which was very good and acupuncture which good for short term pain relief but didn't last long. The Chinese therapist said after about 6 sessions that he thought I was going to need surgery.
Eventually the second visit to neurosurgeon he decided to try surgery. I had a microdiscectomy on L5-L4 and was on my feet just less than 3 hours later. Returned to work about 4 weeks later. I've had a bit of pain since then but the op cleared the worst of the problems, and that was 9 years ago.
Try physio first but if you need an op try a neurosurgeon rather than an orthopaedic as orthopaedic ops tend to be based around fusion ops which often last for a while before the disc above the op deteriorates.
