Im am morbidly obese, and was diagnosed with aurthritis in my back. But the doctor hasn't figured out why my knees hurt, my elbows hurt. I have numbing in my upper back near my shoulder blades, also down my arms to the pinky and the finger next to it. also just sitting here i am getting majorly uncomfortable. in my neck and hips. I get extreme pain in my hip, pevis area when walking, standing, or even sitting on a hard surface, then my thighs get numb. I hate this! I have no filed for disability cause i cant do labor work and now i can barly sit in an office chair for 10 minutes without severe pain. What is my problem? is it the arthritis? i think i have fibermyalgia, but my doctor doesn't know.
