? Glomus tumor: This could be a glints tumor.

Glomus tumor: These symptoms are frequently associated with a glomus tumor. This can be definitively diagnosed with an MRI of the area.

This: Could be several things. Do you notice any changes in the nail besides the pain. Is there discoloration or ridging of the nail? This can be a glomus tumor which is a benign tumor that is commonly under the nail. I recommend an evaluation by a hand surgeon.
