A member asked:

How long should it take for the swelling from phenergan (promethazine) im to subside? lump on upper arm present 4weeks, last 5 days pain below the area too. thanks

A doctor has provided 1 answer

Concerned: Normally after an injection a small area can swell but should rapidly subside. If you have had it for 4 weeks it is possible you are having an infection or reaction. Please see a doctor as soon as possible.
