Fever

For last few days I am having  a sensation of chill. And feeling feverish. Thermometer reading was normal. So I ignored it. Last night it was 100 degree Fahrenheit. Gradually subsided of it's own. I am really worried. I am having minor ailments too often. Sore throat, fever, chest pain.  during puja nowadayss I played cricket and was having lot of muscle  pain in chest and back. Actually I am not able to stay healthy for sometime. What can I do.
Am I too worried about my disease etc. So many people are having coronary artery disease nowadays. Tarun  our next door dweller in kaitha had cabg opn few days ago. I should stop worrying about disease and move forward.
