Sometimes it's a matter of finding the right doctor/medical professional.
My knee surgeon told me 15 years ago, before I even took up running, that I should give up all sports activities and shouldn't even walk up and down stairs when they could be avoided due to lack of cartilage around my kneecap.
When my tibialis flared up the first time, the sports medicine ortho was convinced it was a stress fracture and when the MRI came back clean said "oh, it must be soft tissue, good luck with that" and cut me loose.
It wasn't until I found a PT who specializes in running that I got the tibialis diagnosed and treated appropriately. She's been a godsend for keeping me going through dry needling and homemade custom inserts.
Don't give up on finding the right doc/PT for you. They can be a great help and keep you going if you don't have to stop and heal.
