Called my GP on vacation till 7\1, called my rheumatologist and on vacation until 7/7. It hurts to breath in chest and upper back, no tenderness, no injury or strain. Have been very tired, after work slept from 6 pm-4:30 am. Should I be concerned, I have multiple autoimmune diseases (MG, RA,) or should I just wait it out? Just started dry cough oh that hurts like the dickens, probably cause it hurts to breath deeply. Woke up with this did not have it when I went to bed.
