I am allergic to many adhesives and this has caused an issue with my colostomy. I cannot use Coloplast because I am super duper allergic to something in their adhesive. I currently use Hollister as it is the lesser of the two evils, but even with it, my skin gets so raw where the wafer attaches that sometimes I have to get creative for a bit because I cannot handle putting a wafer back on. I will get welts, sores that do not heal well because they keep getting irritated and more. I use a skin barrier every time I change out my ostomy equipment. Any suggestions on what may help? I do not know of any way to hook an ostomy bag on without a wafer using adhesive. Any idea is welcome.
