Hi, My Name Is Celeste. I Am 63 Years Old

Hi, my name is Celeste. I am 63 years old and have been having bouts of burning pain on the top of my arms. They come and stay for 2 or 3 hour and then lifts. I also have nausea sometimes, hair loss and anxiousness or restlessness. Fatigued but unable to sit when I am anxious.
