All of my muscles were agitated and extremely sore and my feet were freezing, even with socks and many blankets. I struggled to get any sleep I could and finally got up at 05:30AM and moved to the sofa. I distracted myself with TV and had a cup of tea. The muscle disturbances and heart palpitations subsided at about 09:00am. I was able to get up and get some breakfast, but was completely wiped out all day. I was also emotional most of the day. I napped and in the evening went to bed. I slept Ok, but had a multitude of hotflashes then I had to be somewhere in the afternoon. I expended a little energy and broke out into a drenching sweat while I was out for only 2 hours. I went home and flopped on the sofa. No covid prior to vaccination. Covid test post vaccination.
