Hello all,

I recently had a surgery to take out some hidradenitis suppurativa (not sure on spelling) which is an infection of the apocrine sweat glands in my under arm. It would heal a bit for 4 months (not diabetic either) and the doc suggested a would vac. The would itself is about the size of a dvd cover, and while the first dressing hurt like _no other_ the previous two were not so bad due to the use of some white sponges.

Now, they have used something called RENEW which is a white mesh like material, with the dreaded black sponge on top of it. My question is, has anyone had experience with this white mesh material ? Did it hurt to take off ? Reason why Im asking is when I got my first dressing change, it hurt so bad I blacked out from the pain. Thanks in advance !
