Just thought I would share my vaccine experience. I'm one that likes to know what to expect.
After my first dose, the following day, my arm was very sore and and slightly swollen. Now, I had forgotten to keep that arm still for as long as possible after the shot which resulted in the soreness. Also, that following day I had a slight headache but I'm a migraine sufferer so it's hard to say if it was from the shot or not. I was also very tired yet had no desire to take a nap. Day two after the shot my arm felt nearly back to normal. So it was basically no big deal. Most of my coworkers agreed that it was no different than getting the flu shot.
After my second dose it was completely different. Keep in mind that 50% of people experience some of the known side effects, in particular after the second dose. I had nearly all the side effects. Full blown migraine, muscle aches, joint aches, fatigue. My arm was swollen the size of a baseball, it was red, hot, itchy and painful to the touch. This time I had kept my arm still after the shot so it was not sore to move around. The aches and pains lasted mainly for just one day but the swelling etc. in my arm lasted 5-6 days. I also had a weird radiating muscle ache that lasted for approx 10 days. I spoke with many people at work about it and most of them had the arm pain/swelling. It was kind of funny because we were all walking around pulling up our sleeves saying 'look at mine'. Many also had fatigue or headache. I only spoke with 2 people that had no reaction at all.
I certainly don't want to scare anyone off. Both my daughters are ridiculously needle phobic (no good reason for it) and even after seeing me go through it they still can't wait to have their turn.
