I have been getting boils occasionally. I get rashes too. Lately I feel tired all the time. My shoulders ache and feel warm. I thought I had a fever but it was slight. Mt muscles seem sore when I walk down stairs. After I clean my house I am exhausted. Just the other day my hand seemed stiff but only a little. I went to work and experienced sharp chest pains. It happened twice and both times it went away after a few seconds. What is wrong with me?
