In reply to dan bulman:
I was knocked off my bike in January this year and have just about sorted my back out now; ended up with prolapsed disk at L4/5 which caused extreme pain down left leg and buttock.
Tried just about every treatment going and ended up with surgery.
As suggested getting MRI done is the first thing to do and doing it privately may be the best option; I went to A&E with symptoms (not being able to stand for long or walk) and doctor sent me away saying that I had probably prolapsed disk and would just have to get on with it.
I had facet joint injections and epidural which sorted pain for a short period of time each time (maybe 2 weeks)
The next option is radio frequency ablation which burns the nerves around facet joints (but not permanently and no loss of function) this work well for me for maybe three weeks.
During the course of all this treatment I tried many other treatments:
Chiropractor was a big mistake and I think he made it worse; I will never let anyone near me with an acupuncture needle again! (especially when they only put needle exactly where the pain is – was excruciating!!) the manipulation wasn’t helpful either.
First physio I went to was poor – I realised that each time she (aggressively) tested my range of movement it made matters worse.
I eventually found a good physio who explained that the only thing you can do to the area is strengthen the muscles around the disk as they ‘turn off’ after injury which makes the matter worse and tried a course of treatment specifically strengthening the area.
Eventually none of this worked satisfactorily so a few weeks ago I have an interspinous implant placed between L4/5 and decompression (shaving the bone away) where it was compressed – this has improved my life massively, it hasn’t been a complete fix but I can walk/cycle etc.
I would recommend trying everything in same way if possible and leaving surgery as last option; there is a million people offering quick fixes to what I had but ultimately it was a ‘mechanical’ issue that only surgery could sort out; for many either the injections or radio frequency will work if physio doesn’t – some people can have major prolapses and it will not affect them much and often the body will recover naturally
