Yip, have never had an injury take so long to heal, hasn't been a fun three months but I'm finally allowed to run for four mins at a time 🙂
if you take ibuprofen, you apparently need to take it for ten days before it's built up in your system to make a difference. My Physio has me doing exercises on the stairs – stand up on my tiptoes and slowly lower my feet down, dropping past the step into a stretch. But I don't know if you've hurt the sane tendon, so might not make much difference.
Oh and the ankle support from boots has been great, worth the £14ish. But get to a Physio asap for proper treatment 🙂
