She was not sure and nobody was able to answer the question. She was not sure if anyone else has experienced this. She was not sure if it was mental health related, was someone experiencing long term like her. She had been experiencing muscle spasm earlier, but not as frequent. She felt something moving on her upper back and a little pressure. Surprisingly since yesterday, she hasn't felt it and she was hoping it was gone. Over the past two weeks she has felt muscle spasms. Some symptoms appeared earlier. She started to felt a little more the past two weeks. She was not sure if it was a digestive thing. She was going through other tests to find the functionality of her stomach, like liver and gallbladder. She was going through other test and the vaccine dose.
