I get botox for TMJ and Migraines in addition to getting botox to treat wrinkles, rotating these treatments it works out that I'm treated for botox for one or the other atleast once a month and was curious is anyone else is this boat? I am not sure if it is best to space treatments out like this or try to get them all done in one day? My main concern is not building up a resistance/ immunity to botox. Any ideas? Advice?
