After surgery you're in the binder wrap thing, you then switch to vest (got mine from Macom Medical) after a week... It was a few days into vest that it got really bad with swelling and the vest straps digging in to it and making it worse that I decided to try my compression T underneath, and it worked a treat!
Mr Levicks opinion is you cannot have too much compression or for too long, so the more the better!
Consider you're investing over £4k in happiness for the rest of your life... What's another £50? Another £1 per year?? - give yourself the best possible chance of getting best possible result - that's my advice!!
