Soreness down both sides of my legs.

I'm finding it hard to walk . When i sit for a short periods. I get up and I walk like old lady in pain between inner thighs down to my calves. Its right near the knee cap. I go to the gym I'm limited to what I do. I can't do jumps. (hurt). I recently gain weight. Wondering if thats. Or it comes down to been 46yrs. I recently got a scan on my one knee but have arthisits (wear and tear). Do I need to go and get MRI? Its a pain from driving then hopping out of the car walking across the road with stiffness..then slowly comes good for awhile..until sit again.

Any extra weight will cause arthritis and the pain it causes to be worse.

Uh, that link was not what I thought it was.  It is interesting.  My advice would be to eat a diet rich in fruits and vegetables and lean meats.  Easy on carbs - make them healthy ones that are complex.  Pretty much like a diabetic would eat.  That will decrease weight and help reduce inflammation and pain.
