Question: im 38yrs old,, have worked construction most my life as a climber eat healthy as possible, don't smoke or drink more than 1 alcoholic beverage per week, recently my knees have been severely hurting, the pains usta come and go and with the help of topical agent and ibuprofen would go away, but now the pain is staying, and growing more progressive throughout the day, and severely when bending and squatting, one thing I must say is for the last 8yrs ive been office and shop worker so I don't climb anymore, but I am on concrete for the most part, I pick good shoes with good cushion, recently it started with one knee and now it radiates from the back of my thighs and down,,and severely in my right knee, and lately I have has spouts of muscle and nerve pains in my upper back, neck, and arms, bad enough local drs have given me steroids to help with the muscle knots, can this be from lack of extensive exercise even though im active daily ? or lyme disease? I drink atleast a bottle of water a day, no pop, just coffee..
