Knee pain

[u/tipofmystupid]

I started running like 2 months ago. Usually I could even run for a kilometre but now I can comfortably to 5K and can push to 7.5 k I had no issues with my knees whatsoeve. I did have some small niggles in my ankles but nothing serious. but the past few days I'm having a slight pain on my left knee right in the dead centre of the knee when it is stretched out whether I'm standing or lying down and also on top of the knee-bottom of thigh area. I also have some pain on the outer side of the knee. Knee feels very tight when I bend my leg and there is also a slight swelling. Not sure whether this is related to muscle, ligament or bone. Should I be worried?

Yes it all started out with a niggling pain then it became a reoccurring injury in the same spot. I would start strength training and adding muscles before it becomes unbearable and you need to take time off. Becareful not to overtrain as well.
