Thank you all for your advice.
It looks like this is not the drug for me 🥺🥺. I developed a cough and burning in my chest and back of my throat then during the night my tongue was tingling with numbness then started to swell so I took some antihistamines and the symptoms improved but 4 hours later returned. Rang 911 who sent an ambulance they gave me some more antihistamines and things improved it was 7.30 am and my GPs open at 8 so they let me go there rather than the hospital. Awaiting a phone call from the Rheumatologist or his nurse. Tongue still tingling a little but feel rough and the cough hurts but my joints feel great..... sods law!
Understatement of the month J! That must have been worrying, I hope you start to feel much better soon.
Let us know what your Rheumy or Nurse have to say, though I would hope we can guess. Could turn out you'd be allergic to all sulfonomides (antibiotic group) so I’d be thinking about asking to be tested or as your symptoms were such having something to make med profs aware, as well as it being listed as an allergy alert on your notes/med profs computer screen.
