qhorsegal - is your leg pain behind your knees, or all over? The reason I ask is because last week I had a strange thing happen. I have never had any problems with pain in my legs, but last week, for 7 days straight, I had constant pain, all day and night long, right behind both of my knees. They were both swollen/puffy in the same spot. I know it wasn't because of any injury because it was behind both knees. I didn't do anything different prior to this, as far as physical activity, so I don't know why it came about all of a sudden. It was a constant pain, and I had to sleep with 5 pillows under my legs and feet every night.
I even bought that Restless Legs medicine because I wasn't sure if this is what people were talking about when they mention having RLS, and I am on a low dose of sub. Mostly, I would just take ibuprofen at bedtime and that would help a lot. But when I would wake up in the middle of the night (like I always do), it had already worn off and I would have to either take another dose of ibuprofen, or just take my morning dose of sub early...and that always took it away.
This continued for 7 days straight. And then after 7 days, it went away all of a sudden and hasn't come back. Very weird!
I have also noticed the stiffness that you mentioned. My legs and feet are very stiff first thing in the morning now. This just started over the last month or two. When I get out of bed I have to walk slowly for the first few minutes because they are extremely tight for some reason, and I can't stretch them enough! I am also wondering if I am just getting old!
Maybe it's a mid-thirties thing...isn't that about your age?
