These seem different to me. I've had two occasions worried about pneumonia. One cracked a rib, doc said need to be concerned about it developing, never happened. Second had something felt like in lungs ~5 days different than anything before. Friend had walking pneumonia i was getting ready to travel. Doc checked for pneumonia, covid etc nope. But gave me a prescription in case got worse. Never used it cleared up a couple more days. Point is I can't imagine anyone not getting checked out and receiving a prescription if so. Especially an athlete subject to testing, why would a doctor recommend over the counter med?
Regarding Fix I guess you could check the archives. But I probably said something like who wouldn't grab a random bottle of unknown substance from their dad's garage fridge. Well in all seriousness I prob would not. However if this were an esay final exam question I'd give Fix a B for plausible BS.
