I had the (real) flu once about 10 years ago when I was fitter and non-diabetic. It was awful and I felt really ill, hardly able to even stand for a week. I wouldn't like to go through that again.
The practice nurse did offer me the flu jab when I was diagnosed T2 last month. She said I would be affected more by flu now that my immune system is weaker. I told her I didn't like injections but would think about it.
I have a real phobia about needles and injections, going back to childhood. I have only had one injection in almost 60 years since my childhood immunisation vaccinations. I don't even have injections when travelling overseas to countries where it is recommended.
One of the reasons I thought I would never get diabetes is because I thought my fear of insulin injections would prevent me from eating too unhealthily. That didn't work unfortunately. But I am determined to keep my condition under control by diet and exercise so that hopefully I won't need to inject insulin.
It's only injection into muscle that scares me. I don't mind the needles into veins for blood tests, and I used to give blood for years.
I did have a flu vaccination once at work, but that year they did it with a high pressure spray through the skin. I would do that again if it was available, or by nasal spray, but I really can't face an injection.
