Consultation for Covid-19 Vaccination.

I have these problems 1. Difficulty in breathing in closed enviornments (clostrophobic) and after overeating sometime...I feel difficulty in breathing more then anyone I know. Didn't get this properly checked up yet but this is my childhood issue and it haven't been serious ever since. 2. My lower back bone is slightly mis placed due to an injury 5 years ago. It hurts to stand up after sitting on a hard surface for a while. 3. My eyes are allergic to pollen so whenever whether changes they get red and itchy and very difficult to deal with until get properly treated with some eyedrops. I am considering "covishield" as my vaccine. Is there anything I should be worried about before getting vaccinated ??
