knee problem

It started with some soreness on the medial side of my right knee. The exact location seems to be at the top medial-posterior end of the tibia. There's a tendon and a little muscle right there that if I sort of palpate with my fingers back and forth I can feel it slide over the bone or another tendon. I can do the same on the other leg but that's not sore. The sore side might be swollen slightly. Sometimes while standing I can feel it slide over the bone/tendon when my leg goes from straight to slightly bent. Pain level for that is pretty low, more of a discomfort but if I haven't iced it for a while it can be pretty tender to the touch, 5-6 out of 10.
A few days to a week after that I started getting what seemes like bursitis in that knee--pressure seems to build up if leg is bent for too long and it pops when straightened. If I then bend and straighten the leg repeatedly the pop lessens each time and feels better after 5-10 bends.
This came about 2 weeks after I started running after taking a month off. I did 6 runs of about 3-3.5 miles, including 3 actually barefoot during that warm week we had. I'm trying to figure out what caused this. I didn't have any knee problems all last summer/fall, my first year running BF/minimal. Did I start out after my month off with too much mileage? Usually bursitis is from kneeling, right? Did the tendon problem trigger the bursitis? Why did the tendon get sore? If this is bursitis now it seems more acute than what I had 25-30 years ago.
I've been icing it 3-4 times a day for about 4-5 days now, not running and trying not to walk/stand too much on it which aggravates it. The only other unusual thing I had been doing was cutting up a tree into 3 ft length and rolling/pushing-with-my-feet the logs down an incline towards the road. It's possible the tendon got bumped but there was no scrape or bruise and I don't remember anything like that.
Thanks for any advice you can give.
 
Hi Randy,

Just catching up on some posts and I saw this hadn't been responded to. Not sure if you have had any resolution of your problem yet. It is hard to pinpoint an exact problem there, but some starting points would be a problem with a hamstring muscle that inserts there (semimembranosus) or possibly a meniscus problem which is suspicious because of the popping and the "pressure" in the knee.

Can you give an update since it has been two weeks and let us know of any developments?
 
Hi Dr. Klein,
Thanks you so much for asking! What I was calling bursitis has cleared up for the most part. Standing and running don't aggravate it anymore but there is still the feeling of some pressure building up when the knee is bent more than about 45 degrees and subsequent popping. In addition to icing, I also tried heat. Not sure if that helped because about the same time (last Tuesday) I also started this massage: with muscles loose and knee bent, holding my knee lightly between my hands and moving them quickly up and down and in circles for 10-15 seconds, in effect lightly rattling my knee. This provided immediate relief that lasted for 10-30 minutes. I continued that as needed and by Thursday I was able to run again without further aggravation.

The tendon problem hasn't quite cleared up, though it's not nearly as tender as it was. The location does match descriptions of the semimembranosus. I mostly notice it when standing and I shift my weight from one leg to the other and the knee bends or twists slightly--I don't know exactly what, I can never get it to repeat. It feels like the tendon is sliding sideways over a (naturally occuring) bump on the bone. It doesn't hurt much when that happens, just a slight discomfort.

It could be my form slipped a bit over the winter and I wasn't bending my knees enough (and wearing shoes--stems--I didn't notice) and maybe not running often enough. Would that cause these problems, running too straight legged?
