not sure is it my new anta shoe giving problem but yesterday went for a brisk walk for 1 hour and walk halfway suddenly my flexor hallucis longus tendon random pain
Today walk can felt the pain but is bearable.
Guess i need to stop running
We don't know how painful it is, but pretty safe to say since walk also got pain let alone jog/run, you'd need to stop for 2 weeks at least and see what happens if acute phase can be passed before you restart any sports activity.. If you wanna try next week is can with brisk walking, only if the pain becomes really super low level. It needs to be dull background pain like 1 to 2/10 before you can start activity as that is the actual route to recovery, But if it flares up during the session or the day after that means you cannot start any activity to load the tendon(s).......ie not ready yet. Then maybe try again the week after. Meanwhile just try to move around the office/house, your normal X number of daily steps.
If really is tendon based, it is quite a long path to full recovery. I dont have any running experience for this since i have never been tendon injured before for running, but i have had scapular tendon(s) pain before due to overhead push training error, easily 2-3 weeks for the acute phase to clear, restarting the activity even if it is just warm up level would aggravate things, so dont bother trying anything too soon. But it is a catch-22, you are supposed to restart activity to boost recovery. But then you cannot restart it if it worsens the pain during or the day or 2 post session.
edit - ok, if count ITBS as tendon based injury, then yeah i have been injured before in running. I grade it as moderate to high moderate in severity then. Acute phase took like 2 weeks to clear acute phase before it was background, but starting running again just over 5km (not a long distance) = re-flare up. So LLST one. Good luck, bloody long.....easily 2-3 months for full recovery in my high-moderate case even with progressive rehab during those months.
Over here, there were folks who lagi took lagi longer to fully recover, but of coz all of us might be different in severity.
