One week after parathyroid surgery, I returned to the YMCA for Silver Sneakers (exercise class for seniors that can be done seated or standing) today (Tuesday). In 9 days I will see the surgeon again and ask if I can resume more vigorous classes. My neck tends to bobble because the muscles in front were cut, but there is definite improvement already. I look like I tried to slit my own throat; my daughter-in-law says I resemble the Bride of Frankenstein. The red slice marks will fade to scars eventually. I wore a scarf with family (lots of children) on Easter but other than that I haven't attempted to hide the marks.
