Hope you feel better soon!
I am not familiar with the monarch sling but I had the TVT by Ethicon a little over a year ago and am still in agony. There is a group, growing larger every day, that is trying to get mesh products off the market. Women and men from all over have commented or posted on their pain, infections and problems associated with mesh after sling or hernia surgery. The Injury Board has a 3 part article(suffering in silence 1, 2 &3) Then there's Truth in Medicine.us.com and various forums (on yahoo look for johnson&johnson then look at the lawsuit filed against ethicon). You may find helpful info at any of these sites. good luck!
