Dear Merry Volunteer, Hello! Thank-you for the inquiry. The doctor ordered a vibrating vest twice per day, for 20 minutes each time. This is while in the hospital, so I assume if it works, he will order one for home use. I thank God for the treatment I am receiving. He also stated that he will test for E-coli again in 2 weeks time. One thing he said that made me feel better, was that my lungs would "heal, in time." Well, I know emphysema doesn't heal, so he must mean all the rest--pneumonia, and the after-Covid delight! Guess the old saying "Time will tell," would be appropriate here. Again, please accept my gratefulness at all the wonderful information you supplied. After sharing the information with other people about the after effects of Covid, it is shocking that not one person knew. You have been a blessing. P.S. I may be released tomorrow.
