I was examined and told that it was just inflammation caused by old injury and shoe rubbing. They didn’t feel anything dodgy so was told that I could leave. I was so glad to get home to have a bath. I can stop worrying now. Apparently, I would have known by now as those who got blood clots knew after a few weeks of having vaccine. It has been a year since I had mine. Anti inflammatory ibuprofen gel should reduce swelling so that fluid won’t collect in that leg. I didn’t even have to pay parking at that time. It was also a lot quieter than I expected.
