Suggest Treatment For Pain In The Left Side Of The Body

Hi Doctor,

I have pain in my left side of the body (head,eye,neck,shoulder,hand,thumb,lowerback,knee,toe) more pain in left knee,toe and thumb) since 2 years.When I checked in september 2009 with orthopedist, he has done neck and back Xrays and said no problem with my bones,my muscles might be weaker and i need to exercise to strenghten muscles.Since then I did exercise occassionally.The pain subsides for some days as if its gone.But,comes back in 2-3 days.It worsens when I bend,lift weights,take stairs.since 3 months again the pain increased and since a month i am feeling tingling in my hand and fingers.Please let me know whether this is related to my nerves.i have been suffering a lot with this problem.Please suggest the treatment.

Thanks,

SBS
