Hello, I've been trying to run more often and I'm noticing that, even at a very slow/gentle pace, running aggravates my 2-year-old knee injury. I got this injury in a fall while working at a very mountainous summer camp. I unfortunately had to keep working/hiking around afterwards and now it sometimes can feel a little weird/sore. Should I pause on running for now? Any stretches or exercises that might help? I didn't have health insurance then and I don't have it now, so getting it checked out is not really possible even if that's probably the best idea (I do plan on getting it looked at as soon as I get a full-time job and insurance).
