Sulfa and bumps: Do not use sulfa again, you are allergic. Would take benedryl 25 mg every 8 hours for 2 days then every 12 hours for 3 days .if you work use Zyrtec (cetirizine) in the AM and benedryl when you get home. Follow up with doctor /urgent care they may wish to put you on prednisone depending how extensive the rash is. From now on let eveyrone know you are allergic to sulfa.
