i had been tested for hypermobility and the lab reports came negative but im still in pain my parent are telling me i am just imaging it help

hi ! before anything i am a minor and english is my second language .

i used to do a combat related sport but stopped after getting told by an sports physician that my knees where a litle funky and should stop doing it.

my joints hurt i cant stand too long so i use leg braces (those basic compresion ones w rods at the sides)

so i spent a year telling my parents "hey im in pain i might have this thing called hypermobility all my stuff fit in its criteria" and boom when i did get tested 4 it lab records said "we looked into all your genes u dont have anything wrong"

and now my parents are saying im doing it for atention and if i just calm down it would be ok.

...what am i supposed to do now im still in pain walking and standing 4 long amounts of time hurts could i have an disability still or is all this really in my head
