Diagnosed with MCTD - How do you manage pain and sleep issues?

Hi everyone, just recently diagnosed with mixed connective tissue disease (mctd). Just looking for support and information on symptoms like muscle and joint pain, chest/lung pain, all causing sleep disturbances! Finding it really difficult at the minute to get relief from pain, fatigue and feeling totally overwhelmed!
Started plaquenil (2weeks ago) and anti inflammatories yesterday. Does anyone have any suggestions to help with muscle pain and sleep deprivation? Or any advice would be greatly appreciated x
