blister

i have a blister on my sole. can see the fluid inside. a bit itchy. itchy is the mildness form of pain....according to my gynae..haha last time when i going c section, i ask him after epidural will i be totally numb or will still feel itchy? coz i super scare of itchy. sometimes when i touch myself i will feel itchy also..its that sensitive. So luckily, c section is totally numb...if not i think during operation, i will laugh non stop. should i burst the blister on my sole? coz its very irritating and itchy. but burst liao will be easily infected ...and i need to walk alot, probably not a good idea. will wait 2 more days and see if it dries up by itself.
