Knees: More than likely you knelt on something that caused small bruises on your knees. If you have this no other place on your body and have no other symptoms I would not worry about it. If it starts spreading then you should get it checked. ...Read more

What are likely causes of mild/moderate knee/lower leg pain only present when running, no swell/tenderness, pain changes spots, pain stops after run?

Shin splints likely: Make sure you are wearing a reasonable running shoe that fits well. A sudden increase in distance and/or running intensity can harken shin splints which is really just an overuse injury. The treatment is to decrease your intensity/distance akin to a dimmer switch to just below the threshold where symptoms develop.

What could cause small dark bruises to recur in the same spots on r knee. Also have pain and bulging veins on back of same knee and tickling on shin.

I have had an intermittent sensation of a cold, wet spot just below my left knee, on the outer side.   Not actually wet, just feels that way. Causes?

Sensation: When people describe things with warm or cold or wet or burning, I usually think about the cause as something neurological in nature, such as a pinched nerve or compressed nerve somewhere.

but, in the textbooks, driving for prolonged periods is the classic cause of blood clots forming in the legs that give changes in circulation/pain/swelling
AND CAN EASILY BREAK OFF, GO TO THE HEART AND LUNGS AND BE FATAL. THEREFORE THIS IS A REASON TO IMMEDIATELY GO TO THE HOSPITAL as a general textbook situation. ...Read more

Ecchymosis: This pigment could be due to breakdown products of red blood cells which stain the skin brownish yellow. Perhaps a tiny capillary or vein ruptured spontaneously and painlessly in the area. This pigment usually fades away gradually over a few weeks. Your physician can advise you further if necessary. ...Read more
