Hi @kgoodwin9, thank you for allowing me to share your private message in this discussion. I think it may be helpful for other members who may also be looking for answers and allow them the chance to share information they have learned.

I have large areas of calcinosis and many the diameter of golf balls. Ones on my buttock are about 3 1/2" x 5". Very large. Been to many local doctors in Florida, Sarasota and to Mayo Clinic in Rochester for autoimmune but they took pics of the calcinosis at that time 11/2015. Since then they grew larger to the sizes I indicated in memo. Are there any groups that have this issue that I should join?

Hello @kgoodwin9, I'm not aware of any support groups for Calcinosis but I did a search and found discussion of calcinosis on buttocks that may help. It was started in 2010 and has 2 pages of posts with the newest from 2014.

Anyone have any information they can share with @kgoodwin9?

Thank you,
John
