A Little While Ago I Was In The Kitchen Cooking,

A little while ago I was in the kitchen cooking, when all of a sudden I felt as if something was wrapping around my right side kind of tightly, then my right side just lifted into the air as if I had done that isometric exercise where you press your arms into a doorway, then they rise. I pushed it down, but it rose again. I am 59 years old, female, and I have scleroderma. I just feel anxiety and a slight headache now. What should I do?
