Rest, I’m afraid! When I did mine, I was hobbling for quite some time. Then while you’re resting, research some rehab exercises. I went to a BUPA running clinic & got a load of exercises. Standing with your toes on a step & raising & lowering – that sort of thing. I still do my stretches every day while cleaning my teeth – multi-tasking!
It took me 3 months to be able to run at all. Then I went to a proper running shop & did gait analysis & got some proper shoes – I did mine running uphill in old squishy shoes.
Do not rush your recovery! Take it seriously as it IS serious! (Says, someone, who pulled something in their hip yesterday running across a plowed field & who should be a quarter of the way through a half marathon this time tomorrow…)
