Hi Tgmaine,
Sometimes the skin around your incision becomes dry and itchy while healing. Although it is okay to put lotion or cream on the surrounding skin if it is uncomfortable, you should
not apply anything close to or on the stitches or incision without the approval of your surgeon. It normally takes four to six weeks for the incision to fully heal and close. You don't want to risk infection by applying a product near an open area before that time. Some of the more common creams and lotions used on a healed incision are Bio-Oil, Vitamin E Oil, E45 Cream, Palmer's Cocoa Butter Lotion with Vitamin E, and Coconut Oil.
The one exception to the guidance in regard to applying products topically over your incision is a product called
ACTIVE AntiMicrobial Hydrogel Spray. This product contains hypochlorous (HOCL), a compound made naturally by your body to promote healing. It can be applied to your incision at any point during recovery - it's a germ fighter as well as a healing and moisturizing agent. Discuss its use with your surgeon before using it. You will find a link at the top right of the page in a sidebar ad you can click on.
The protocol for wound coverage varies from surgeon to surgeon it seems. I was advised to keep mine covered and after I showered and it was completely dry, recover with fresh gauze. I'd be inclined to want it covered if there are open spaces as you described. Consider sending your surgeon's care team a cell phone photo of your incision to get their opinion on wound care. I think it will give you peace of mind and I'm certain they'd be happy to advise.
For sleeping...pillows, lots of bed pillows did the trick for me. I kind of surrounded myself with pillows of varying firmness and found it comfortable to rest an arm, or leg, on one. I felt rather swaddled by having them close on both sides. I'ts all about comfort and whatever it takes to get you through the early weeks.
Best wishes for an easy recovery!
