Frozen Shoulder on Left, Starting on Right

Hello-

I am a 50 year old, female who has had frozen shoulder on left side for 3 months. Almost completely frozen with 15 degree mobility. Pain is very intense, worse at might, when lying on back, lying on left side is impossible as pain becomes immediately deep and boring. Have light numbness in entire shoulder, forearm and fingers. Minor neck pain and stiffness. Also have Dupuytren's Contracture in both hands which are generally cold. Lots of popping and clicking in shoulder. Slightly better with light movement or when soaking in warm tub. I have tried Arnica 30C, 3 times per day, alternating with Arnica 200C every other day for 2 weeks in pellet form. Maybe 10% improvement in pain. No improvement in range of motion. Started taking Rhus Tox 30C wet dose which I made by adding 3 pellets to 500ml water and then I shake 10 times before sipping a tablespoon from bottle 3 times per day. I sip directly from bottle and make a fresh mixture each day. On third day and maybe another 10% reduction in pain with no change in range of motion. I also have heavy fatigue. Should I continue with Rhus Tox or is this too minimal an improvement? Trying hard to be patient but pain and fatigue are pretty extreme and keeping me almost house bound. Any advice would be much appreciated. Thank you.
