Just small clarification. The allergy would be do to sulfa- as in sulfonamides drugs.
Alicia as some suggestions have been given here is some things that may help expound further:
1- Have history already of allergies? It sounds as if you do. People can often develop progressively worse allergies to things they have already been allergic to in the past.
2- Any exposures to anything new in your environment?
3- Have you checked your local pollen index's to see if you can associate any recent spikes with specific pollens with worsening of your symptoms. You should be able to find ongoing records for your local online.
4- This was already touched on, but have you started any new meds recently? Or if you take meds for the asthma or allergies already, have you stopped or changed doses of any of those recently?
5- Mentioned already, but yes, try and see if you have changed anything in the home recently (soaps, detergents, any aerosolized items, topicals, makeups) also check your air filter in your AC/central air, replacing or cleaning that can make a big difference.
By carefully and systematically going through this rough checklist you may either associate or be able to isolate what may be causing the new allergies. It can help your doctor with suggesting any new allergy meds or histamine blockers. After all that and you still don't have relief, seeing an allergist would be recommended or even dermatologist. I hope this helps Alicia and you are able to get some relief soon.
