Ok I wasn't going to go but after reading I think I am going to go to doc. My left arm has a huge lump on it its not red but it hurts. What do I tell the doc I have insurance but I really don't want it to be on my record So should I tell him I want it off the record or tell him im shooting b12 which I don't think he will believe or should I just let the insurance handle it what if i need it cut open is something like that expensive anybody have experience with this?
