Shaunashrum, I am praying for you and Eric.
Have you tried any of the following? Ayurveda. Traditional Chinese medicine. Naturopathy. Integrative medicine. These four branches of health sure helped me. Some medical doctors (M.D.s) practice integrative medicine. You can find one on IFM.org I don't know if this would help rhabdomyolysis or not, but worth a shot. Good luck
Shaunashrum, I am praying for you. Dear Father, May Your love and protection surround Eric, even now, a month later, so that Your healing will is done. Give Your Comfort to Shauna and reassurance that Eric is well. In Jesus name we pray.
