When you "jammed" your finger, you probably suffered some soft tissue
damage. While your finger is not fractured, the edema is the result of inflammation within the joint.
The edema is preventing the flexion of the finger. It will remain sore to the touch until it is healed in about 6 weeks.
Take over-the-counter NSAID
, if that is not contraindicated for you. You may take:
400 mg every 4 hours OR 600 mg every 6 hours OR 800 mg every 8 hours.
If you do not see any improvement within the next 4 weeks, make an appointment with your family physician and ask for a referral to an orthopedist.
