My thumb nail bed is sore to touch. if i bump it....the pain is excuriating as if i am going to pass out. what could be wrong? mri shows nothing.

Skin infection: or paronychia (infection of the cuticle) with spread into the nail bed- requires immediate evaluation. with

Consider...: The most painful nail abnormalities are blood under the nail from trauma, infection and a benign glomus tumor. These tumor are quite small and can be easily missed with a standard MRI of the hand. Many MRI sites are set up for larger body parts and not nail disorders. You may ask your Doctor for a re-evaluation and then a repeat MRI using a small hand coil, with and without contrast.
