WOW is my big word! My hubby and I, and not young, got what you are talking about. My hubby has double lung cancer so hit him much harder. Told of course, the viruses going around are viral. We did our best, with all the symptoms that you mentioned for 10 days and then decided we needed help. Our family doc. was on vacation so went in to a clinic and I guess by these number of days passing an x-ray was given for hubby stating that he had pneumonia, and myself thought as having possible bronchitis. Long story short both went on two separate prescriptions of anti-biotics for bacterial infections and finally after a month we are now feeling we have beat this monster. So many unknown viruses circulating that the medical field are not prepared for how to treat - try this, try that, and hopefully with lots of time all will return to normal, and I guess we experienced such and I hope time has now remedied your problems. Tough road to travel!
