Need Help with Joint Pain Relief

does anyone know of any ways to help with joint pain? i’ve tried numerous things and nothing is helping and my guardian won’t bring me to the doctor because she doesn’t believe anything is wrong with me. i’ve tried tylenol and ibuprofen and that hasn’t helped, i’ve tried heat on them and it hasn’t helped, cold made them worse, i’ve tried gentle exercises and that made it worse, i’ve tried tumeric, vitamin b, vitamin d, vitamin a and c and it worked for a couple weeks but not it doesn’t (plus i throw up every vitamin i take now) i’ve tried warm showers, i’ve tried stretches, i’m trying to change my diet (but it’s hard) i’ve tried cbd and it takes an edge off but it’s still painful, i’ve tried everything i can think of and i’m so lost and i’m in so much pain that i literally cry about it now. does anyone have any ounce of advice even if it seems stupid? i need help
