Thats the nature of chronic pain,insidious
Its very possible that your problems might be posture related.
Maybe you should meet the plaster cast halfway-a sling
If all the conventional methods fail to alleviate it then maybe alternative therapies might be worth a try.Its just not quackery IMHO.
Naturopathy,Reflexology,Aromatherapy
They all take a different approach to Modern medicine which can't be a bad thing if the pain is still there
All the way down to magnets which by the way a friend of mine who is riddled with chronic pain/arthritis in her joints swears by
