Hi I m 26, 5 4 and 199lbs. I ve been trying to loose weight with diet and exercise. Recently my knees have been getting very bothersome. They swell up and have pain when I bend them like when I sit down or squat to pick something up. Also my hips are causing me problems as well. My right hips hurts and sometimes causes my leg to go numb and the nerve section in the dimple over my butt-ox keeps swelling and hurts to touch it. This has been going on for a couple of months and makes it hard to exercise. I want to lose weight, but its getting discouraging. Suggestions?
