In reply to Cats:
YES, YES, YES. For those with the commonest forms of back problem, this book is the absolute pinnacle of spinal self-help. However, the book lists a set of criteria to help you decide whether this is the right treatment for you. Take care to go through this.
I recommend that you see a Chartered Physiotherapist either through your local NHS where there may be substantial resources, or directly to a private practicioner.

Regarding drugs, intramuscular Voltarol works wonders to calm things down after an injury. However, I suspect that you are past that if you have had trouble for 6 months.
It might be different in englandshire, but here, a pharmacist can give you Paracetamol and Dihydrocodeine. Boots do one. This is the absolute dogs-bollocks of over-the-counter painkillers. It can also be taken along with NSAID like ibuprofen or voltarol/dichlofenac.
Heat-treatment may help you. At hospital physio depts they use infra-red. You can do a home-spun version by placing a hot water bottle (if you can find one these days) over the injury site. Note that the injury site and the pain site may be diferent locations.
Probably there are a number of strands of treatment you require and these should be mutually supportive and not considered in isolation. This is likely to include the following.
- Pain relief
- Anti-inflammatory drugs
- Medical investigation
- Physiotherapy
