Just to get this out of the way, I have a Dr's appointment tomorrow, so I'm not asking for Medical advice or whatnot in any "Tell me what to do to fix this!" kind of thing.
I've been slacking on my running/jogging this winter because I hate running on treadmills, and greatly prefer running outside. Going only once a week or so for the last couple months.
Well, Spring is finally up on us up here, and I've been gladly running my 5 miles (Or so) a day again, without having any real issues of any kind. Careful to stretch/stay hydrated.
Well late, late last night (After the clippers spurs game was over for quite awhile, so very late) I went out for my run, and felt fine the entire time. Was a bit sore when I got home, but I figured it was just fatigue.
Well, now whenever I go up or down stairs, my knee has very sharp, intense pain in it, only when straightening up after a bend. Does this sound like an ACL tear/pull? or another ligament issue?
Its only in my left knee, and only when I'm going up/down stairs, on the downward pressure as I step onto the stair. It is hurting badly enough that I've just been going down the stairs one at a time, keeping my left leg straight :P
I hope its not serious, don't want to be sitting on my keister for the next couple weeks or something.
Honestly You kind of hit the nail on the head. It sounds like a minor to moderate ACL injury (either tear of pull). Nothing too serious you'll probably be up and running in 3 to 4 days. I had the same kind of thing happen during the last football season and it wasn't too much of a problem.
Its just kind of strange because I finished my run and felt fine all night, then woke up this morning and bammo, problems with the stairs :P
Ive had similar happen to me. I know it happens a lot of new runners or people who are getting back into it. You set out to run a mile, you feel fine so you run 3. Next morning you realize you should not have ran 3.
