As stated previously, I got my 3rd Pfizer shot(booster) on Friday in my left arm and the flu shot in my right arm.

The next day, Saturday both arms were a bit sore, very  similar to when I do an intense, strength training work out and my muscles are sore.

The arm that got the COVID shot was a bit more sore than the other arm.

I didn't have a fever but did have a tiny headache. I have a severe form of lupus like arthritis (auto immune disease) that causes pain and extreme sensitivity in several areas and this seemed a tad worse.

If I hadn't received the shots, I would probably not even have noticed it and chalked it up to a bad arthritis day because I didn't sleep well(which actually was the case).

Larry will understand this. Most weekday nights, because the markets are trading all night, I will not sleep much. Often sleeping a couple of hours, then waking for a particular model run, then going back to sleep for a few hours........or just waking to check on prices/markets.

The condition also affects my bladder and I often have to pee 4+ times at night. 

The early/mid 90's, when markets only traded during the day were like rest paradise!

So I state this because LAST night, for the first time in months, I actually slept solid for 8+ hours(with the exception of using my pee bucket on the side of the bed a few times for a minute).

As I result, I feel Wonderful!

The right arm is no longer sore and the left arm is just barely sore if you push on it.

The pharmacist, who knows my meds, that include a pretty high dose of prednisone, which is an immunosuppressant, said "you're probably going to need a 4th shot in 6 months because of your condition"

I already knew that.

Bring it on!
