Had linq monitor placed 1 wk ago now coughing brwn phlegm chest pain fever wound was draining clear liquid can i treat at home or should i see a dr?

Unrelated: The link monitor has nothing to do with your other symptoms. Brown phlegm, chest pain and fever is very worrisome. Could be infectious (pneumonia) or potentially a blood clot in your lung. You should seek a healthcare evaluation and they can check out the wound healing from your Linq implant at the same time although that sounds more or less OK. Don't try to treat/diagnose this at home.
