Hi jillybee,
I had some hardness and heat in my diep reconstruction, about 2 months out from op (at the same time as a throat infection)... the hardness at it's worst encircled most of my reconstruction and was quite sore, like a big flat pebble of the beach or breastfeeding engorgement! I looked for info and thiught it could be fat necrosis.
I also had a lot of redness in adominal scar I was told all related to the strep throat I had picked up so close to op, lots of antibiotics and I tried massage etc.. it then just disappeared after a week or two.
Not quite the same thing but I know its such a worry/ nuisance /disappointment when something you're just getting to terms with goes a bit awry and I think really so little post-op info out there that we can easily access...
I'd say always ask the hospital in my experience they try to reassure you and have usually seen most of it before...or the BCC helpline are great .
Hope it resolves soon
