Hi, I hurt my left hamstring while running in the winter due to not warming up properly and likely not stretching the hamstring enough. It feels much better now, though, and I have tried running on occasion. However, running noticeably makes it feel sore, and if I were to keep running, I think I would injure it again, so I have assumed I should continue resting it. Is this true- is the best I can do now to take up another sport (biking has been fine), wait, and continue only when it does not feel sore after a trial run?

I haven’t found another sport I enjoy as much as running, and I haven’t seen a physical therapist for this yet because I really did not enjoy seeing one for a different issue in the past.
