Hi there. I have had this problem for awhile and the doctor doesn't seem to think much of it. Thought I'd try asking here and see if there are any different opinions. I just want to be sure there is nothing serious.
I am a full time student and, of course, there are stairs I must go up/down on a daily basis for my classes. I have no problems going down the stairs as far as I've noticed. However, when I go UP the stairs I feel a gradual pain in my knees. The farther I go the more it hurts. Usually by the time I get to the top it hurts pretty bad, but then it fades away. With this though, it causes me to breathe rather hard/heavily for awhile until it eventually goes away. A friend said that maybe I'm just out of shape, but this is halfway through a semester with no improvement whatsoever. I am puzzled. I am thin, 5'3, and 120 lbs and only 20 years old. Not really sure why I am having these issues.
Another thing I have noticed is I seem to have a fast pulse when doing nothing, and I noticed that after going up some stairs my pulse slowed down (Unless I felt it wrong). Not sure if that pertains to it at all, but yeah.
Any help would be great!
