Is 3 wks after surgery too late to begin use of a compression garment and how long per day should I use the garment?

I had a leg & arm lift as well as liposuction. Both incissions are like a T scar. The compression garment was irritating & prolonging healing at the junction of the T cut. It's been 25 days, since my surgery. I just found a compression garment that doesn't irritate the part that's still healing between my thighs.
