Hello @hotfooted -- Thanks for the private message. Your question "why is there no specific Group Category for Erythromelalgia? I know Mayo Clinic has doctors and treatments for this condition, so I am puzzled" is similar to questions others might have been thinking so I wanted to address it here.

There is discussion on Connect for Erythromelalgia that I think you are familiar with which is the discussion that I am posting your question in here:
> Groups > Autoimmune Diseases > Erythromelalgia
-- https://connect.mayoclinic.org/discussion/erythromelalgia/

I'm tagging Colleen @colleenyoung our director in case she wants to add any thoughts or corrections. New groups are added to Connect based on activity and need. Since I joined in 2016 Connect has made a lot of significant improvements and added groups and discussions as the need arises.

As you mentioned in your question, Mayo Clinic has doctors and treatments for the condition. Our moderator @kanaazpereira shared a good description that talks about what Mayo Clinic offers earlier in this discussion. Here is a link to Kanaaz's post: https://connect.mayoclinic.org/discussion/erythromelalgia/

I would also like to mention a feature on Connect that most members probably are not familiar with - the search function. There is a good discussion on how to use search to find conditions, discussions and more here:
