Saturday she did not feel up to par. She was sick Saturday night.  Sunday she was okay. Monday, she woke up with a headache that she could not even touch her head or hair.  She then had to take some medicine because her head hurt so bad that it was making her sick. Today (07Apr2021), she got up and went and worked out and thought she could do workout class.

Caller adds that, like she said, she could not touch her hair.  She took 800 mg Ibuprofen but it did not make her feel better.  At 9 am, she took the Zofran because she was feeling sick to her stomach. Caller adds that she slept until 11. The headache subsided but the whole day she felt drained and could hardly move. Caller clarifies this was this past Monday, 05Apr2021. Tuesday, 06APR2021, caller was okay. Caller adds that she was pretty normal, and then today she woke up at 4:30am and thought since she had a good day yesterday that she was going to go back and workout and do her crossfit.  She has been working out for three months. After her run, she was pouring sweat, which is not normal for her. Caller states that the sweating went away and just every once in a while she can not catch her breath and has kind of a little cough. Caller can not catch her breath and has a cough: caller adds it could be the pollen, she does not know. Caller then adds that she feels like she does not have energy today, normally when she does her workout she feels good the rest of the day if that makes sense. Caller adds that she wants to make sure this is normal. Caller states, like she said, she has been working from home since they sent her home back in March so she has not really been around a whole bunch of people and she has been really healthy.  All of a sudden, she took the second shot and she is just not feeling the same.
