Arthritis???

About 2 years ago I started having some soreness in my left knee once in a while. It got worse to the point where it would hurt/ache so bad it would wake me up in the middle of the night. It was constant but much worse at night and in the morning. It's a dull to severe ache that jumps around my knee, front of my thigh and hip.

I'd take 1-2 Motrin and that would take the pain away 100% for 12-24 hrs.

I started to get worried after taking Motrin every day for a month as that stuff's not good to take forever.

Went to the doctor. X-rays showing nothing and she gives me Prednisone for a week. The stuff worked ok but not as good as the Motrin. She said if the pain lasted over the next few weeks or got worse we'd do an MRI.

I started taking Glucosamine, doing some weight lifting on my legs, and specific stretching that would help if the problem was some type of Sciatica.

Between all of this pain dropped to none during the day and about 5-10% at night and early, early morning.

This week it's started to flair up again. I'd kept taking the Glucosamine but hadn't been doing the stretching or weight lifting as much.

Anybody else had similar stuff?
