Oh Bryn, I hope it will be all okay for you. Sure hope it is not infected back there, I'd hate to see you go thru more. Please let us know when you can.
My hand turns blue also, this heat is not good either. It is very hot here today, summer is horrible where I live. My hand turns blue/red/swells, just need a transplant......
I keep a wrap on it that my therapist gives me, I have several of them this way one is always clean. The wind/heat and a/c hurts when it blows on my arm/hand so it is protected. This wrap also helps the swelling.
Hope your evening is nice
