Am i going to lose my legs? what do i do?..?

I wiegh aprox 320 pounds and my bff took me to hot topic and made me purchase the tightest G-string i have ever seen before, it looks like it was made for a 90 pound 13 year old.. anyways later that night i got hot watching "the dukes of hazzard" and i decided to get y along with it so i tryed on the new G-string and then fell asleep watching southpark. The next morning i totaly forgot about it, lived my normal life and went to sleep again, and this process happened for about 6 days and then i relized i was still wearing the new panties. My legs where a very dark red and up to my belly on it was a almost gray color. I then tried to immediately remove the undergarmets but they wouldent budge, i tryed using soap, grease, lotion and a large variety of other lubricants to remove them but they still wouldent come off! i then resorted to trying to cut them off they where so deep into my skin i couldent get to the angle to cut them with the blade. anyways does anybody have a suggestion to get these darn things off?? And if you are in the medical field what do you thinks happening with my legs?? PLEASE REPLY FAST.
