Hello

I am after some advice. I have noticed a smooth white patch on the back of my left tonsil. it's not angry looking. I have been to my gp twice  and they its nothing and to a private ent consultant who felt my tonsil took a look and said he thinks it's a bit of muscle tissue. I can't help but worry though I don't know when this patch first started but it feels like something is caught in my mouth/throat on occasions and my left handside can feel drier. my tonsil is also bigger then the other again they say nothing to worry about. Am I being overly anxious?
