HI I have gone through your mail as you said that your wife had developed a red congested spot on the side of uvula
after tonsellectomy operation which bleeds on touching. I am suspecting that your wife is having post operative slough in tonsillar fossa which is whitish in colour and area adjacent to it is congested and reddish spot which bleeds on touch. you should contact your concerned E.N.T.doctor to find out the real fact, it may be secondary haemorrhage due to secondary infection or it is reactionary haemorrhage and accordingly that should be managed by your doctor. Thanks.
