Mod-Portion Achilles Paratenosis

Hello, I would really appreciate some advice, as I’ve been dealing with this for the past three months and don’t know what else I can do. I’m also wondering if anyone has gone through something similar.

I’ve been seeing several physiotherapists, and they’ve told me that if the pain is around 2–3 out of 10, I should keep running. The issue is that sometimes the pain is less, and other times it’s worse, so I’m not sure whether I’m progressing or going backwards.

I had an ultrasound, which showed that my Achilles tendon is fine, but there is fluid in the tendon sheath. Apparently, this is rubbing against the tendon during movement which is causing me pain.

They are now suggesting TECAR therapy, but I’m unsure about it. I’ve already tried shockwave therapy and haven’t seen any improvement.

Any advice or shared experiences would be really appreciated. Thank you.
