I'd come off all the meds completely and rest completely for a fortnight whilst rubbing comfrey oil/ointment into the affected area daily, comfrey is very effective as an anti inflammatory in connective tissue. I'd seek out some nerve mobilisation exercises too, if you lie on your back with your leg straight up in the air and rotate the ankle this should be a start, use your quads to straighten your leg as this will relax your hamstrings.

It sounds to me like you're a bit unwilling to stop running, which is the first crucial mistake injured people make. It sounds like a recovery/repair process is yet to initiate itself.
