Osteoarthritis Knees

I was told 5 years ago that I had osteoarthritis in my knees. They did test and said I did not have osteoporosis. That was odd, but that is what they said. Then I was also told that I had hyperthyroidism. The PTH numbers were already high when they told me this several years ago and the numbers are now 336 and that was Feb 2020. Pandemic hit right after a needle biopsy and ultra sound on my thyroid and no cancer and there is a nodule on the thyroid and swollen. Doctor told me to let them know if I have trouble swallowing, cough a lot and other issues. Most of those I did not have but I definitely noticed over the year of the pandemic on lockdown that I have hip pain now and sometimes my toes curl and lock up. I live by myself and this does concern me.
