Bruising and swelling are normal in the suctioned areas and usually increase slightly after the removal of any tape or foam. The bruising will decrease over 3-4 weeks, but may last as long as 6 weeks. The majority of the swelling will be gone within the first 3-4 weeks. However it may take 6-9 months to disappear completely.
Answered by The Community. Making the world better, one answer at a time. How long it takes swelling to go down after a bee or wasp sting varies greatly from person to person, as well as from insect to insect. For example, wasp stings generally take longer than bee stings to subside in swelling.If you are allergic to one and not the other, though, it may take much longer.sually it takes a few hours for the swelling to go down. If you  have a large local reaction to the stinger, the swelling will  increase for the next 1 or 2 days but will s â¦ ubside after the course  of about a week. 24 people found this useful.
