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!
