Yes, it is a partially torn Peroneus Brevius tendon. Came off my Comptrainer following a training session the second week of March 2012, sat down, changed my shoes and then for some reason turned to the right instead of the left and “wacked” the lateral portion of my right foot on the base of the Comptrainer. I was stunned and needed to sit down again to rub my foot. Did so for 30 seconds or so and continued on with life with the thought “it will go away”. Base of 5th metatarsal developed significant point tenderness but no deformity or discoloration. Continued with my run training on a treadmill that really did not hurt running but afterwards developed a burning sensation more posterior to the base of the fifth metatarsal. April 11, completed a 10 mile run on the treadmill with the increase of burning sensation following running. This sensation would also develop at work when I was rising up on my toes, doing lateral movements. Sleeping on my right side was not possible due to pressure on this location. Decided to back away from running for two weeks. No change. Appointment made with local Podiatrist. X-Ray at end of April reveals no fracture. Given oral steroids and review by Physical Therapist in which the manual foot tests were negative. Questions raised on what the problem is. Two weeks later I was given a steroid injection at base of 5th metatarsal. Got ultrasound from Physical Therapist. No change. One week later, another steroid injection and a couple of additional ultrasound treatment yielded no improvement. MRI performed on the 24th of May. Returned to the Podiatrist who stated I had a partial tear of the peroneous tendon and needed to be immobilized for 4 weeks. I got a boot on but can swim and bike if no pain is present.
I will have to see how fast this mid 50’s person heals.
