I am a very healthy, active 49 year old woman. I have been exercising and doing many sports (swim, cycle, weight lift) since I was a teenager and have never stopped nor slowed down. I have low blood pressure, never smoked and I drink wine occassionally with dinner. Last week I developed a high fever with my body feeling extremely cold - it took hot tea, layers of clothes and a wool blanket to feel somewhat warm again. The strange thing was that my chest, just under the breasts, felt very tight - like someone had tied a belt around my chest and was pulling it tight, more prominent on the right side. I could breathe but could not take deep breaths because it hurt very badly. I didn't feel like eating much of anything - just smoothies and ice cream. After two days the fever and chest pain went away. The following day the fever and chest pain returned, then went away again. But still, I feel the pain around my chest and it is pains me to take deep breaths. I still don't have much of an appetite, and especially after I eat my chest hurts (tightness) and deep breaths are impossible. I don't work, have no kids and have no stress in my life - so I know it isn't anxiety. I'm wondering if I should see a doctor?
