Dear Sir

I am sad to hear of your pediment as I also have a similar problem and have had it for some 30 years. With this said I may be able to help if you have not already tried the following.
If there is a physician that practices trigger point therapy in England he or she may give you some relief. The mother of this technique was Janet Travell x president John F. Kennedy's doctor. She was a sort of friend of mine when alive and a really supper lady, unfortunately she passed away some years ago. Janet authored two books ( Myofascial Pain & Dysfunction the Trigger Point Manual) #!. upper body #2 lower body. I suggest you locate these books and read on the chapter that addresses your problem. If you wish to chat about your problem you can email me at [email protected]. I may be able to give you some further pointers. Good luck.
