Possible femur stress fracture

You might have a stress reaction or a "minor" stress fracture. As someone who's had a stress fracture in the femoral neck, I would advise you to get an MRI done asap! Or just stop running for 6 weeks and see if it heals.

I had a stress fracture in my femoral neck last fall and ended up getting pins. Fast forward one year and now I have a stress reactions in my other femoral neck. Luckily, I was smart enough to stop immediately when it started to feel similar to last time and it only ended up being a reaction and not a fracture. Better safe than sorry!

I had a femoral stress fracture near where your adductor inserts, my pain gradually kept getting worse and worse until it really couldn't hold the force being transmitted through my legs whilst running. The test wasn't positive for me either. I didn't have an MRI either as it was diagnosed on a clinical basis. Either way, if there is pain it's probably a good idea to take some rest and time off. I swam furiously and then gradually added in biking and epiliptical. All in the recovery was about 6 weeks. You might want to get your bloods analysed to see if you have sufficient calcium, Vit D, magnesium and iron, and potentially look at new runners which really absorb shock well.
