My daughter, age 22, physically fit, non drug user, etc. is experiencing red swollen fingers and toes that are painful. The occurrence comes on quickly with no warning and usually last several hours. This last time it occurred, it has lasted six days. There has also been tingling and numbness of the toes and finger but no these symptoms don t always occur with the redness. She had MRI of neck and head to rule out pinched nerve or something else. Do you have any ideas. I am trying to get her in to see a rheumatologist.Susan
