Do you know how to cure hurt fascia?

About 40 days ago, I went out in the gym. I tried to change the high of exercise machine, and suddenly it hit my thomb. I thought it was just simple, so I didn’t care. I just waited until thomb to be recovered, but it didn’t I went to hospital and hot physical therapy, but still it doesn’t be cured. I don’t know why. Whenever I bend the thomb, it is really painful. I heard fascia’s damage is more worse than bonds’ damage. Do anyon experience it? Please give me some tips!
