Hello, I have been getting the flu shot every year from the same brand (Flu Quadri) without any side effects. However, last year, I wasn't feeling too well on the day when I got it. I don't know if this was the reason, but after 2 hrs of getting it, I felt my chest tightening up and found it difficult to breath. This only lasted for a very short while. However, the next morning, I woke up with a severe muscle pain all over my body, so much so that I had trouble getting out of my bed. This pain continued for the entire day until at night time, this symptom suddenly disappeared completely. I didn't know whether it would be ok for me to get the flu shot this year or avoid it completely. Would it be ok if I get the flu shot on the day when I'm feeling my best this year? Or should I avoid the flu vaccine completely this year after experiencing these side effects last year?
