Welcome to the forum Jules

I hope you'll find it very helpful in every way - it is consoling to know there are other people with similar problems and to have a place where everybody understands the difficulties of living with chronic illness and you can talk freely about whatever's bothering you.
There are not many people with an MCTD diagnosis but that doesn't matter - a lot of people have various issues with overlaps and lupus variants and the same symptoms such as Raynauds even if they don't strictly speaking have a formal MCTD diagnosis. Treatment is much the same too.
We do have two people with an MCTD diagnosis who don't post any more because they are very well controlled or in remission
Let us know how we can help you and join in as you wish
Bye for now !
