I just turned 25 and been having problems with losing weight and bad chest pressure and shortness of breath. I had an ekg done,xray blood and urine test which all came out normal. Now i also just got a impacted wisdom tooth extracted which was infected for a while. I just recently got it pulled which did at first alleviate chest pressure but woke up the next morning with the same issue of chest pressure and shirtness of breath. Now im taking amoxicillin and am wondering if its just anxiety or did i have a infection from the tooth into my body and if so if i continue amoxicillin will it help the possibe infection problem? Oh btw i did have a problem eating due to stomach tightness as well for a bit of time and my infected wisdom tooth was impacted. Even before the extraction i have been tired from small exertion activities when i used to work out.
