Modmom, it sounds like you know that Flonase and Advair both contain fluticasone. I was on that combo for a short period early on and broke out with acne like a 14 year old, so for me at least there was a systemic effect.

The package insert for my Flovent (fluticasone) says it can 'cause soft tissue injuries,' that's ligaments, tendons, etc. It can retard healing, when I used a higher dose I bruised easily and small cuts took a long time to heal, but you should be healed by now. What criteria are they using to determine it has not healed? What does the pain feel like? Can you pinpoint it and describe it easily or is it kind of diffuse and hard to tell exactly what hurts?

What are your neuropathy symptoms?

Did the same Dr prescribe both your meds? I think you are probably right in your feeling that the fluticasone is involved, can you get by on a lower dose of Advair or stop the Flonase? What does your Dr say?
