WW, it's nowhere near bad enough to need lidocaine. Ice cubes might work.
So far I have just the usual little needlestick bruises, but was stunned to find one that is 14 colors and approximately the size of Canada....which is what I mean by it being easy to run out of room even though you have endless fat. That is one big ol' area I can no longer use. Not to mention that bruise is going to take MONTHS to disappear.
