Posterior tibial tendonitis?

Hi!

I’ve been having a lot of pain in my right foot posterior tibial tendon. I took two weeks off running and it was feeling a lot better, so I ran 3 miles but was in so much pain!

Stopped running again, been doing a lot of icing and theraband exercises, also have a compression brace for it… is there anything else I can do?

Hoping to be ok in time for Chicago in October but I’m worried 😟
