is this normal??

Uhh!! So first of all, I wanna say that I'm not asking for medical advice or like a diagnosis or anything, I just wanna know if this is normal, and how to bring it up to my mom if it's not normal

I (14 ftm) am starting to get kiiiinda worried
I'm constantly in pain; not horribly (well, not horribly all the time...), but still, pain. My joints hurt all the time, to the point where it hurts to bend over to pick something up, it hurts to stand for more than 3 minutes, and it basically hurts to do basic motor functions (walking, running, picking stuff up, [with hands and like bending over n stuff], etc).
I also wake up in an unbearable amount of pain. Like, so bad that I have to lay completely still in bed for at least 20 minutes before I can actually move. It slowly gets better over the course of the day, but if I wake up and have to go right away (like if I wake up late for school), it hurts that bad the whole day

I also get random pains that hurt so bad it feels like my limbs are being crushed; they usually last for about an hour at a time

I told my doctor about this, but she said they were growing pains. Thing is, I only told her about how my joints hurt. My mom started getting pissed at me when i started saying more, so I stopped

I also already tried telling my mom about this, but she got mad at me saying I was being dramatic and since I was only 14 I couldn't be dealing with any of this

I'm not on any hormones or anything by the way, if that changes anything; my mom's super transphobic, so I won't be allowed to do any of that until I'm at least 18

I just want to know how to tell her if this isn't normal, and try to convince her to actually get me some help. If this is completely normal though, then I guess I don't have anything to worry about. Might need to invest in those arthritis creams though.
