Get a 2nd opinion. I had a similar diagnosis by a physiatrist in 2003, based on the reading of bone scan results not an MRI. In the end, the problem was soft tissue and not bone. The activity seen on the bone scan was misinterpreted by the physiatrist.

Cycling may NOT be a good idea. You are putting weight and pressure on fractured bones.

A friend of mine recently had a femoral neck fracture (different spot but same area) and couldn't even water run for six weeks - just swim.

Hip injuries are nothing to mess with.

I wish you speedy healing.

My wife had a sf of the pubic ramis a while ago. Her doc (who is a runner and a great doc all around) had her aquajogging for 3-4 weeks before moving onto cycling until week 7 or so then elliptical machine to week 9 or 10 and then a slow reintroduction to running.

I am a man but also have a single sfx of the pubic ramus bone. It started back in the middle of March, so I am now at about week 11 in the recovery. However, I didn't find out I had the sfx until the beginning of May. I tried to run a couple times in March and early April but have stayed away from running since.

My doc has advised me to not run--that's it. We specifically talked about cycling and he explained that because this is a repetitive use injury and is specific to running, it should be OK to cycle. Even with that, I've been cautious about cycling until a week ago. This weekend, I rode twice, once for 45 mins and once for an hour. I'm feeling fine. I'm also walking at this point with little problem . .. maybe just a little tightness in the groin area. In addition, I'm swimming three times per week.

I hope to get back to some running in the next 4 - 8 weeks. Crossing my fingers. :-)
