My middle finger, is swollen, from tip to base. swollen to the point, skin is tight, hard to bend. it is not red, or warm. has been this way since tue?

Swollen finger.: The symptoms described are very suggestive of infection. You should be seen by an an md soon.

Swollen finger: Have you had any injury? That it is not warm or red, speaks against infection, but still a possibility. Any other problems such as pain in joints? Fever? I would see a doctor to have an exam, maybe xray and some blood work.
