I had the problem on my thumb when I went. Neither dermatologist did anything to test what it was, they both took guesses. Literally said, "Hmm... that looks like _ _ _ try this cream. I went to the dermatologist with a referral for other skin things my doctor wanted me to have checked out and treated. I don't know what other people's experience with doctors is like, but as I've said before, mine have not been all too good. Especially for some reason with dermatologists. They've been incredibly arrogant A-holes, on many levels.
When I went to the first I was asked when filling out paper work if I wanted a full body cancer screening. I said, "Sure," as I'd be an idiot to not take advantage. When the doctor saw me he looked at the problem I was referred to him for, but didn't do the screening. I asked if he was going to do it, and he said, "Why, are you worried about anything specifically?" I said no, but I'd like to be checked. He literally looked me up and down for about 2 seconds, said, "Turn around," did it again, and said, "You're fine." My adrenaline pumped a bit at that and while he was starting to write something down I said, "You know, I actually do have something I'm concerned about." I have a small patch on my back that gets itchy all the time, for more than a year. It's a tiny spot, and it's always the exact same spot. I described it in detail, he told me to turn around, looked again for about 2 seconds, said, "There's nothing there," and then went back to writing.
Maybe it's a NY thing... Though I've had some good experiences with GPs here. As fer nickel, I was using steel and switched to nickel to see if it would help. I'm confident the strings have nothing to do with it. Repeatedly injuring the finger is what the problem has become. It's been 3 days since I've used it at all, and it's beginning to heal.
Going to add something else... though I don't want to get into my MD rant. I've had many, MANY bad experiences with doctors, and I don't make them out to be the gods that some people do. They're humans. One particularly bad experience happened about 25 years ago when I was in college. I had gotten into acting and music took a back seat. After doing a children's show (I played Jiminy Cricket

) I started to have throat problems. I had a sore throat every day, as well as swollen glands and other problems that were going along with it. It was chronic, and it killed any acting I was doing. It became impossible to project, and it started getting me really depressed. I started going to doctors a week after it happened and continued for the next year and a half. My issue got to the point where I had to carefully choose my words throughout the day, and felt limited to about 200. The more I talked, the more it hurt, and life was getting really tough.
What the doctors did throughout that year and a half was the same thing over and over - GP, they'd prescribe antibiotics, it wouldn't work, and they'd send me to an ENT. ENT would run tests, come up with nothing and prescribe more antibiotics. And that wouldn't work, and then I'd make the rounds again, with different doctors. None of them could figure out what was wrong, and as I said - then other problems started. Stomach problems, depression, fatigue, swollen lymph nodes - I started to think the end was near. One day someone educated me about antibiotics, and freaked out at the amount I had been taking. At that time I thought of them like vitamins, though I was of course taking them only as prescribed. Long story short, I stopped all treatment, stopped going to doctors, started looking into some holistic solutions... and within 2 months what had plagued me for over a year and half disappeared completely.
I understand that many people have different experiences, and I'm happy for them. I don't like to "treat" things though unless absolutely necessary. I spent all of yesterday in the hospital with my brother who is 4 years younger than me because they believed he had a stroke. Doctors have been "treating" his high blood pressure with about 5 pills a day now for almost a decade. He's on about 4 other medications for other issues because doctors are his "go to" solution. He isn't getting healthier over time, he's getting much sicker.
And so my MD rant starts seeping out anyhow...
I put a lot of time, thought, and education into my health decisions. Outside of my finger and a sketchy lower back that I'm working at healing, I'm in perfect health, and happy to not be dependent on any medications. At 57 years old, these days I consider that an accomplishment.
