Welcome to HW irsinaz.
Im not sure what form of arthritis you have (I have AS) but thought I would let you know what I take/do to help myself.
I walk and do yoga, I take probiotics, multivitamin, fish oil, calcium, vitamin D, folic acid. I also take Methotrexate and Prednisone ( I also have Crohn's disease) the Methotrexate is for the AS as well as the Crohn's. When my AS is flaring I use heat pads, hot showers and walking to get mobility back. Sorry if this is'nt much help to you, remember we all suffer differently and what works for one may not work for another. Good luck in your search for relief.
Jo (also scared of the biologics)
