I had gyno surgery 2 weeks ago and now have the bandages off. i am pleased with the results but there is a large hard swell going from my nipple to where the incision was for the lipo under my arm, causing a bump. Is this scar tissue or just hard swelling or is that the same thing? i was told and read to massage any hard lumps and was wondering how hard to massage as i don't want to cause and damage and prolong healing. thanks.
