hs runner recovering from a muscle strain?

hi everyone, i’m a freshman in high school and after a super successful cross country season... this past december i developed a dull, numbing, ache on the inside of my leg, just below the knee that developed into a shooting pain when i was doing harder workouts. i stopped running for nearly 2 months yet still felt it in my leg. i then went through the lengthy process of being diagnosed, wearing a boot on my leg (which did very little), and going to physical therapy. i regained strength in my leg and the intensity of the ache certainly lessened. by late march, i was confident in myself, especially since i wore therapeutic running tape constantly, blocking the pain. however, track season began a couple weeks ago, and while i feel okay on my runs a few times a week (i’m taking mileage and pace slowly) i’m worried about the long term effects of this. while most of the time i merely feel soreness in my shin, which i suspect from the tape, there’s an occasional ache. in addition, i’ve been worried about my form when running (as i have high arches as well) and while my pace is moderate, i get tired after .3 miles whereas a few months ago i was running 7, feeling a bit tired but great! any advice from experienced runners, athletes, or coaches about how to have my leg feel perfectly normal again or how to progress? it would be very appreciated as i’ve felt stressed about it recently. thank you for reading if you’ve made it this far. xx
