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 Good luck
If the pain is from a blood clot, I don't know what to say. But I know that acupuncture can help with pain. Obviously you need to get the blood clot taken care of though.
Dear Father God and Lord Jesus, I pray that you will heal Beth Lauren's leg from the blood clot as well as her knee pain. Please allow her through your grace and mercy to grow stronger. May the blood test results be in her favor. On a different note, I pray that you and Lord Jesus will give her the emotional, mental, and spiritual strength to deal with her dear son's mental illness and behavior. Please allow her to get the help that he needs so her daily life will stabilize. May she meditate on Matthew 11:28-30 so that you, Lord Jesus, can lift her burdens and allow her to have some rest. In Jesus's name, I pray.
