It's been around 2 months when I first noticed this on my back, noticed it as went for a massage and I could feel it. Tried sorting it out self at home but DH said it looked like it had already been done as had a sort of scabby looking part in the middle.
Anyway, 2 months on and it's still there, I've left it alone all this time and just had DH checking to see it it heals / gets a head on it. It does feel like it's gotten bigger in that time and is certainly more painful
