Brief history. Moved north to West Yorkshire in 1974 (aged 29). Started with beathing difficulties. Had allergy tests and a course of desensitisation injections, which worked, but whenever I caught a cold, it morphed into a sore throat and chest infection leading to gasping for breath. Major attack 1st October 1983, in hospital for 12 days. Treated with oxygen and prednisolone. Over the years a few bouts a year. Treatment has been courses of antibiotics and steroids. I use DuoResp Spiromax 320/9 dry powder inhaler (and Salamol inhaler, when needed, not often).
I also am in my 6th year of Permanent, though asymptomatic, Atrial Fibrillation after 22 years of Paroxysmal AF. My only medication for that is an anticoagulant, Warfarin being my choice. My diet is vegetarian with some fish.
Both my asthma and Atrial Fibrillation normally cause no problems. Coincidentally having had every appropriate jab going since the pandemic, I have not any colds, so no asthma problems of the old kind.
In November of 2016 I had an emergency operation to remove my appendix, during which operation my heart-rate went over 190 beats per minute. I was kept in hospital until it had dropped below 70, whch took 3 days, during which time a hospital doctor queried why I hadn't been prescribed beta blockers, and despite telling him I was asthmatic, he prescribed a low dose of Bisoprolol. 7 weeks later the first of the side effects appeared, painful urticaria. While being weaned off Bisoprolol, the second side effect, a constriction of my lungs with chest pains occurred suddenly. I was in a Pharmacy at the time, and an ambulance was called to take me to hospital. There was no infection. It was relatively short-lived and after numerous nebulisers, once I started on a course of steroids I was discharged on the 3rd day in hospital.
My peak flow is normally lowish, around 350, but I did notice on Saturday just gone that I could breathe deeply, but didnt check my peak flow. On Sunday and Monday I had awful headaches and my ability to breathe was reduced. By Monday night my plan was to sit in a chair all night. I did to 3am at which time my breathing had become worse and my chest hurt when I breathed. I called 111 and an ambulance was sent. I only spent 14 hours in hospital before the chest pains had subsided and I could breathe normally. I had phials of blood taken 3 times. The consultant said the blood showed signs of inflammation, but that I had no infection. I was referred to heart specialists who could find nothing wrong, apart from AF with my heart. I had taken my own INR on Monday morning when it was out of range, but on the high side at 3.7.
I don't expect anyone to come up with an answer to why my lungs constrict without infection. In the first case it was Bisoprolol. In the second case I have no idea, apart from some form of allergy? Because I also have Foot drop of my right foot, I order food deliveries from a supermarket as the foot drop causes balance problems. My diet hasn't changed. Any ideas?
