Hello Doctors, as I had mentioned in my previous query, twice this has happened : First incidence was a week ago, when I was lying in bed ready to sleep, when suddenly I got up to switch off something. I started feeling very dizzy, in fact even when I tried to lie down, I felt even more dizzy as if the walls of ceiling were turning or my vision was going round and round and then also felt pain in my groin region. A week before this episode, I had woke up with extreme pain in my grown that eased out gradually on going to toilet, so thought it was gas. Today, felt very tired from morning, when I woke up from sleep, felt dizzy. I had taken precaution dose of Covishield vaccine on 25/08/22, so less than a month. Can this be due to side effects of the vaccine as even the blood related clotting issue was supposed to be monitored between 4-28 days from getting vaccine? I am very concerned, since I never felt dizzy like this before these two episodes.
