hi, as mentioned by you, it is sad to hear you have now bias against doctors. Well to help with your pain I will give you some tips. As mentioned by you that you have a severe chronic back ache and even you have RA. let us take one by one each of it. Back ache - as you mentioned you had 3 surgeries of your back what was that and why they were performed. Also, before of after the surgery did you try physical therapy. As physical therapy will help you with therapeutic ultrasound therapy and TENS therapy for controlling of the pain symptomatically. Also, then you need to strengthen the muscles of the spine and the core. As one has to understand that the muscles are the support system of the joints and any weakness in the muscular system will lead to pain in the joints. As the body has to adapt and heal on its own, that is the greatest creation of the god, what Medication and physical therapy can do is to provide support till the body takes its role for action. RA - for RA, you need to do a regular exercises like - meditation, breathing exercises and general body exercises. Exercises should be focused on improving the muscle strength and maintaining the joint mobility As we need to understand that the body is a self healer and any external effort is symptomatic help till the body takes its own call to recover. Also, metabolism of the body varies from individual to individual and only you can improve the metabolism of your body by performing the exercises. There is no external device which can help improve the metabolism. Self induced effort is the only one which can regenerate the bodily functions and provides the optimum relief.
