My suggestion is. (and sorry if you have done all this before!)
have a proper rest for a week or 2, just maybe walk. let things settle and recover
increase your fitness for the next few weeks using low impact eg bike and swim only.
get a gait analysis and check you are running in the right trainers.
I know it sounds like a rediculous backward step but start again using a beginners training program, even go as far back as a couch to 5k to retrain the muscles and not overdo it. (i have done this myself following injury!)
(not sure what your age is buti found Bruce Tulloh's running over 40 book to be excellent to follow for training programs)
take up yoga for flexibility
visit a different physio or better still an Osteo as they are a little more holistic. many running injuries come from problems in other areas.
check your running style to make sure you are not overstriding, hunching shoulders, leaning forward from the hips, etc etc
run 75% of your runs offroad
and Chill Winston. . .
