Tibialis posterior MUSCLE issue, not tendon

I have tib post muscle issues I have found it hard to improve but most improvement with cortisone iontophoresis to the area as well as some calf soft tissue work and needles

There are also exercises you can do to prevent recurrence

Your issue is probably different though if you are post surgical

Can you ask surgeon?

Was yours caused by anything specifically? I talked to the surgeon about it several months ago, and he said if it didn't get better, I should be fitted for orthotics. But I don't think orthotics would help nor do I want artificial support if I don't need it. This was the same surgeon that gave me the go-ahead to start running 4 months after the surgery. I then went and saw a different surgeon (a top NFL surgeon) and he told me I needed at least 7 months of recovery before running. So I don't know if he would be good when it comes to issues that are related to running.

No cause that I know of but I do tend to “overpronate”. I think that is why they recommend orthotics for this but I got some and $900 later I just had really bad blisters and clunky feet and no improvement. That said, some people swear by them. But I wouldn’t rush for them if you aren’t keen.

As well as the tib post strengthening exercises, I was told general ankle stability can help like wobble board or whatever.

If the surgeons haven’t been super helpful maybe get another opinion from a non-surgeon? It just sounds like if you didn’t have the muscle issues before surgery it’s probably related.
