Is there anyway to stop the itching after adominal and flank liposuction?

I had 5.2 L of fat removed from adomen & flanks. I'm on day 6. Bleeding has stopped. I have a swelling, numbness, & A LOT OF ITCHING. I used some Benadryl Spray for Skin Itch and pain but it doesn't help much. My first post-op appointment isnt for 3 more days. I am moisturing after my showers. I have great skin elasticity. I am 32 years old. I also use Aveeno shower gel for ithchy skin- Chamomile. The itching is SO BAD, its torture.
