For the last month+ I have noticed a very medicinal odor that occurs after wearing my flange for 1 day or so; it actually causes my clothing in that area to pick up the odor as well. It is not the result of output.... not sure why this is happening and/or what can be done about it. I switched products (was using Convatec) as I thought maybe I had developed a strange chemical reaction with what I was using but the new company product (Hollister) causes the same problem. I am planning on calling both Convatec and Hollister to see what they think. Any thoughts from you all are appreciated! I really don't want to have to change the flange/pouch every day as the cost will definitely add up!!!
