First off, i rarely get sick. once or twice a year maybe. but this year, i got hit hard with a cold in august that lasted two weeks, i thought that it went away, but then i got hit really hard with another cold about a week and a half later. and haven't really gotten over it. every time i think that i'm getting better, i get a relapse again. it's not a very bad cold, just a stuffy nose, sore throat sometimes, occasionally a headache and a cough. but then a few days ago, i got a fever and the next morning i woke up and my heart was just pounding, about 110 per minute, i don't know if that's like, really really fast, but it went away as soon as i ate breakfast. idk, should i go to the doctor? it could be walking pnemonia i suppose. what should i do and has anyone else had this?
