behind knee pain when running after 40 mins

One of the most common knee injuries among runners would be patellofemoral pain, or runner's knee. But since you say that the pain goes away after running, I would rule that out. I would bet it's some form of tendonitis and should go away if you give it time to heal correctly.

Make sure you are working on hip/quad strength, your knee could be compensating for imbalances.

What are some good quad exercise?

Sounds like vaginitis.

if it's "pain" behind the knee it's most likely a pulling or pinching feeling. this is the result of a tendon being compressed, or, worse, the hamstring. put a tennis ball on a stack of books, and lay your achilles on it. move your leg in circular motions to massage it, and lay off on the static hamstring stretching for a few days.

ok thanks will do. sometimes it feels like the pain is actually on the upper part of my calf, or even to the inside of my upper calf. It is extremely weird. But its not really pain, just this extremely weak feeling. since I can run fine for 30-45 minutes no problems I have been tempted to just run 30-45 minutes twice a day. I guess that is bad lol but it gets my mileage in.

This is not runner's knee. Runner's knee is in the front of the knee running underneath the kneecap. I have had this pain before. It is actually a calf issue. your calf is really tight and it is pulling on the insertion point behind the knee. Calf stretching and rolling out the calf will help.

This sounds like what I have going on. Did you continue to run on it before it went away? I tried a week off and that didn't help. Any thoughts on calf compression sleeve? thanks

This could be a good news bad news type thing. Without a note of obvious trauma this doesn't sound like ligamentous or meniscal injury. Try doing a Thessaly's test on your own to determine if you do have any meniscus damage (Google it). You won't be able to test MCL, LCL, PCL, nor ACL ruptures on your own. My guess is you have some hamstrings tendonitis. This is a wear injury that isn't going to get a lot better without rest and increasing strength and flexibility. I recommend doing yoga for a week and hitting the gym and doing real lifts. You can run until it becomes painful. If you feel like this is anything more go to your physician. Also, don't take NSAIDs. You want your muscles to grow and NSAIDs will prevent growth.

There was no trauma involved and I just did the Thessaly's test and all went well there. What cross training can I do with Hamstring Tendonitis?

Calf compression is hit or miss. I like calf compression for recovery, while I asleep I'll wear them. It might help, it also could be hamstring like the other post stated, but with the description of the pain I am pretty sure it is the calf. I would not do any strengthen until the pain is gone. The thing is you can run 30 to 40 mins without pain, so my thought process is what is happening at that point. I would think it is the tighten of the calf through the run from impact, old shoes, etc.

I did run through mine, but I wasn't training for anything and didn't run over an hour. If you are close to a race I would think you could train through it, just be care with any insertion point issues they can progress to cause some serious problems. If you are just in base phase, I would suggest taking a couple days off do a lot of stretching, putting heat on it beforehand to loosen it up. Go to a massage therapist, and see if you have any knots in your calves. run the next couple days just 30 40 mins and then go from there. If there is no change then it might be a ligment issue like ACL or something.

I'm not an expert by any means, but I have dealt with a lot of injuries. Hope this helps

Do you think it is tendonitis or just tight muscles? I feel really tight in my calf and IT band, but feeling discomfort in calf and behind knee. I can walk with no issues, but running is discomfort and there is no way I can do speed days like this.

Thanks I really appreciate it!! I'll try the calf compression, I am desperate lol. I'm going to get a massage two days from now. Injuries suck, thanks for your suggestions!!

Stretch your hamstrings for like 5 minutes a day and work on that ass muscle

Do you think your IT band is causing this issue?

A couple of points to make. Firstly, from what you've described it sounds more like a tendonitis than it sounds like a myositis. Secondly and more importantly, I am a physician, and I am capable of making these diagnoses only to patients whom I interact with in a more personal manner. You are not in that category, and if you really want a definitive diagnosis you need to visit your physician.

To answer your question concerning appropriate training, the reason that this is happening (in my opinion) is that your tendons are taking more work than they can handle and they are sick of it. In order to correct this, they need to be stronger. There are a few ways you can accomplish this. First of all, I recommend you only do exercises that take you up to a level 5/10 pain (not discomfort but actual pain, if you experience no pain and only discomfort you can do whatever you like). As for the exercises, squats, deadlifts, lunges, leg press...etc. Stay away from the machines (quad extension, ab/adductor, glute thingy). Those all can put your muscles in eccentric positions that can actually strain tendons far worse than they currently are. This does however mean that you can run as long as it isn't painful, running slower and shorter isn't going to decrease your healing that much. You probably want to get some hill work in though (keep that short and fast to actually build strength). Lastly, STREEEEEEEEEEEETCCCCCCCCCCCHHHHHHH. I don't typically recommend stretching for runners, there isn't enough evidence to suggest that excessive flexibility does anything to benefit runners and I'd rather them spend that time doing core or weightlifting. In your case however, your tendons need to be relaxed, so stretch them.

I highly recommend the advice that these physical therapists give out. I recommend you scroll through their video list and find whatever they say about hamstrings and incorporate it into your training in the future at least until you heal up.

Cheers.

thank you so much for the info!! :)
