I have suffering from chest pain (in middle of chest or below the throat. I was smoker earlier but from last few month I quit smoking, When I smoke much chest pain increases. In normal I did not feel pain but when I twist my body then I feel it. When ever I want to start doing gym but after 5, 6 days I feel little fever. Approx 98 or 99'F and chest pain and throat infection increases. After taking rest for 4, 5 days it decreases. I am having this pain for last five year. I am pure vegetarian in food habit, not even eating egg. I have search that the problem I am facing which having most the symptom similar to pleurisy chest pain. It might be due to bacterial or viral infection in chest. I want to continue gym but unfortunately I cant do it. Could you please suggest on this.
