How to recover from painful ligament or cartilage problems?

I am 62 years old. I am a right hand person.

Around 9 months ago, my left middle finger¡¯s middle and bottom joints 
around the knuckle areas, started to be painful, particularly in the 
morning. When I tried to bend my middle finger, I feel the joint movement 
not smooth, kind of snap and bounce like a toggle switch.



I am unable to fold and curl my middle finger back to touch my palm, like 
trying to hold a fist. When I put my finger in hot water, the joint
movement 
is smoother and less painful. I am taking Glucosamine Hydrochloride
(1500mg) 
plug MSN (methylsulfonylmethane 1500mg) daily, but showing no help.



My doctor has X-ray and blood test for Rheumatoid Arthritis. Everything 
tested normal.



I have tried and see different physicians, physical therapist, orthopedic 
specialists; none offer much explanation or help. Except one athletic
person 
suggested I have the ¡°soft bone¡± problem. This soft bone is suppose to
be 
part of the ligament and cartilage tightening problem. But he did not
offer 
much solution for my problem, except that I should have physical therapy 
exercise.



After 8 months of daily left middle finger pains, now my left thumb starts

having the same kind of pain too.

Can anyone out there offer any suggestions and recommendations? Thank you
so 
much.
