Can ayurvedic medicines help with rheumatoid arthritis?

Hi doctor,

I am 24-years-old and I have been diagnosed with Rheumatoid arthritis for 4 years. I am currently taking Prednisone and stopped taking immunosuppressants recently. Rheumatoid factor, anti-CCP, and HLA-B27 are all negative. The only diagnostics I have is from an MRI of the wrist, showing bone erosion and swelling. I am 6.23 inches and I weigh 127.87 Ibs. My arthritis is changing from place to place, but two places are constant, right knee and left wrist. Both have liquid retention and stiffness and I feel cold and pain. Other body parts like the elbow and fingers are affected too but are less frequently. My stool is like diarrhea. I wake up with a lot of mucus in my throat and I have asthma. I am a very vata person with a lot of thoughts and anxiety but meditation has helped me a lot with that. One Ayurveda doctor said I have a kapha-vata condition. My diet consisted of very oily, meat, and unhealthy dieting for many years, I have recently changed into a vegetarian but I take fish sometimes. I experience more pain in the morning with stiffness. I tend to be a lazy person, but I try to be more mindful. I would like to know about the ayurvedic treatment and a healthy meal, water, and sleep plan. I am a student and I cannot afford expensive medicines. Please advise me with good affordable Ayurvedic medicines. Thank you.
