Would you go to a doctor about this?

A couple weeks ago I had a small lump in my right armpit (pea-sized). It hurt a little bit, and it’s gone now. But now I’ve got a very similar one in my left armpit.

I have extremely sensitive skin and a lot of skin allergies, and I’ve been known to get irritation in my armpits from shaving.

I know Fluther isn’t the place to get medical advice, but mainly I’m wondering if it’s reasonable to be worried about this. I have pretty extreme health paranoia so I don’t really trust my own judgement on these things. I know there are lymph nodes there which is my main concern. What I want to know is, would you, likely a much less hypochondriacal person than I, go to a doctor about this? We have insurance so money’s not an issue. I just don’t want to go if it’s nothing to worry about because I’m really trying to get over my health paranoia and my tendency to go to the ER or doctor at the drop of a hat. I know it’s always better safe than sorry but there is such a thing as being too safe if the paranoia interferes with your quality of life.

Thanks.
