Hello Joanne. After radiation for throat cancer and having Covid, my vocal cords (VCs) paralyzed. For a year, mucus was trapped in my lungs, as the VCs diagnosis had not yet been made. During my journey, I had a bronchoscopy which found MRSA and other rare (they said) lethal bacteria. Hearing "MRSA" is very scary! At times, during that year, it felt like I was dying. Being on many different antibiotics did nothing to eradicate the MRSA. This, after many sputum tests. Long story short (sorry) I ended up getting a Trach tube to relieve all that mucus, and it has been a miracle. The mucus is right there to cough or suction out. The point is this: The last few pulmonologists and an Infectious Disease doctor told me that having MRSA in the sputum is perfectly NORMAL. It is to the point that we must rely on ourselves in many cases, to figure things out. I sure do not understand all the different opinions, advice, etc. I am keeping you in my thoughts and prayers for wisdom in your situation!
