Some shortness of breath, occasionally feels like heart flutters and sometimes it is rapid but only for a few beats, low grade fever in the afternoon sometimes, joint pain, difficulty sleeping. I am not a smoker, I don t feel like I have a cold, I am appropriate weight and exercise regularly. I have had a slightly elevated RA factor in the past. The joint pain has been there off and on for a few years but the rest is new. I have no health problems other than migraines and take no meds except maxalt as needed.
