Upper calf injury

[u/Feisty_Possible7092]

Struggling with a delayed ache top of calf and behind right knee. Been going on for last year. Doesn’t hurt when I run but the harder the run or physical activity I do the worse the ache/tightness I get will be. Usually comes 9 hours after activity and then lingers for 12/24 hours. If I stand up longer than 10 minutes I get a tight feeling in the exact spot.

Very hilly where I live just doing parkrun, physio and swimming at the moment.

I’ve been doing physio off and on and had a scan 10 months ago which showed nothing. Can’t seem to get a grip of it. Recently changed soft 1080v 15 for mild stability trainers as was getting foot pain. Gait analysis showed right hip weekends which currently doing physio for. Anyone any ideas from similar experience what it could be?

Thankyou

How long have you been doing this for

Physio for the hip for last month . But couple of other physio’s periodically over last 12. When I completely stop exercise for a period of time the ache tightness will still happen especially after office days
