Welcome, Silver! You've definitely come to the right place if you're looking for a kind and supportive group of people.
Do you know what connective tissue disease your GP thinks you have? What symptoms alerted you that something wasn't quite right?
Hopefully, your visit with the rheumatologist will be englightening and help you on your way to treatment and management of what ails you. And again, welcome to the forum, and I hope you are doing okay!
