Hi for more than 15 years I have had nodules, which started in my legs, then through the years also in my arms, they are syperficial nontender unless i pressed them hard. now from a couple of months ago im feeling nodules in my penis. My last blod test were normal a year ago. I know i have togo and see a Dr, I was wondering which Dr should i go and see? and what do you think this might be, Lymphoma may be? I have no malaise, no loss of weight, and my appetite is good
