My right arm has sun-damaged skin from years of lying in the sun in my youth and many miles of driving a car. Hard nodules keep appearing as well as white pussy or clear fluid small blister-like things. Sometimes when these latter things are developing, there is swelling, soreness and redness. These symptoms disappear almost as soon as the fluid is released. I have an apt with a dermatologist at the end of August? He has a description and referral from my G.P. Do my symptoms sound reasonably harmless or do they need attention earlier than my specialist appt? Thanks, Rhonda
