I think my hearing may have changed a bit in the positive direction even without hearing aids recently. In listening to test tones, 8 kHz was perhaps about half of 6 kHz, and I couldn't hear 10 kHz. Now, 8 kHz is closer to 6 kHz, and I can hear 10 kHz at abut half of 8 or 6 kHz. Why?
I think I know the answer. It will surprise you. I was just hospitalized from Thursday - Monday for a ruptured appendix. A drain was inserted, appendix not removed yet, the abdominal bugs identified and IV antibiotics given. Since hospital release, I report daily for a dose of IV antibiotics. I follow up with doctors (Infectious Disease, General Surgeon, Primary Care). The drain will be removed AFTER the CT scan confirms all the gook is gone from my abdomen AND lab work confirms infection eradicated. Here's the catch. I think my appendix ruptured like 18 months ago. This is when I moved all components off three racks, moved racks away from the wall, and my custom installer installed my in ceiling Dolby Atmos/DTS-X speakers. Install completed Thursday. Friday I put everything back. An hour or two later, I got real sick, nausea, throwing up, with abdominal pain moving over to right side, next to my right hip replacement, severely. I laid in bed and couldn't move, the pain was so bad with any movement. I got up in the morning maybe 50% better, and as I got out of bed, I had a terribly painful muscle spasm at the right upper thigh, I could see the muscle spasming and moving down the right upper leg. I assumed I did too much physical activity, and in a few days I was fully recovered. Over the next 18 months, I had occasional (about every several months) flareups of some pain at right abdomen which went away in a few days. My family doctor a few times wrote this off as muscle spasm (I'm ditching him for sure, he never ordered tests, and 10 days ago saw me and did nothing). About two weeks ago symptoms came back and did not go away, hence I ended up in the ER last Thursday. By the way, when I initially reported to the ER, my temperature and blood pressure were in normal range. The ER doctor said she had seen this once before, where the patient was very strong and walled off and controlled the infection from a burst appendix for some time! For some time I have had some headaches daily, particularly watching movies/tv or reading. Since they administered antibiotics in the hospital, the headaches have practically disappeared. Right now I feel better than ever! But I surmise this may have affected my hearing at least some.
I will continue to demo hearing aids, and when I select a pair to buy, I will ask my Audiologist to give me a new hearing test first, to see if the results differ from earlier at all, and then to program the hearing aids for my then current hearing loss!
I am wondering if I should be in Ripley's Believe It Or Not! However, I can only surmise when my appendix ruptured, I don't have actual medical proof!
