Yes im sure there is - its quite normal to feel nervous in certain situations - attending a dental appointment - giving a speech - or lecture - recieving an award - if you notice at some award ceremies of tv such as globes ect - have a little look at carefully at the screen ..while those women and guys even it they are famous actors or personalities are not emmune to the creeping or rising chest rash and neck !! the only reason we can just about notice it is they are heavily "made-up" using cam make up powders ect ...to cover that and they are also having surgery to stop underarm sweating ..all the little tricks of the trade ...everyone gets a bit nervous from time to time ..take a few deep breaths and forget the rash ...or if you feel very uncomfortable im sure the dr could give you something just to stop that happening if you had an imprtant event to attend ...dates and stuff like that are triggers for it ..but its nothing to worry ...
