Hot off the presses, a little good news about anosmia, loss of smell. https://archive.is/dqhGD
tldr: While colds, flu, sinusitis can all cause loss of smell due to one mechanism, obstruction and swelling, Covid 19 has another mechanism. It attacks the substrate supporting the olfactory nerves. This can even lead to loss of the peripheral olfactory nerves. The somewhat good news is that they regenerate. The not so good news is that it takes a long, long time. And though it doesn't say so here, possibly in some cases the substrate destruction can't be overcome.
Finally back to 100% after 10 days. Day 2 was the worst and the other days werent bad. Lost my sense of taste after 1 week and 3 days later its back to normal. Seasonal flu and I didnt need to get tested for anything. Took plenty of vitamins (Zelenko Prototcol) and rested and stayed well hydrated. YOU CAN DO IT!
