Welcome @wfwcooks. I moved your question to this existing discussion about antisynthetase syndrome:
- Antisynthetase Syndrome: Anyone else? https://connect.mayoclinic.org/discussion/anti-synthetase-syndrome/

I did this so you can connect with others like @nancykay1888 @jamieray6812 @tstefanelli @allie7764 @cbozzolo28 who can share their experiences with you and respond to your question about if anyone has been able to successfully get off oxygen and recover.

Does he use oxygen all the time?
