Could I have POTS syndrome? Symptoms and Suspicions

I have osteoporosis at a young age and a 5 cm tilt in my hip to the right and i have really stretchy skin and flexible muscles and bones so the reason I wanna talk to you is that I have suspicion that I have pots syndrome I have all the symptoms I found online and I did try to see my heart rate on my watch while laying down then standing up and it was rise of about 30 beats every time I tried it and I do feel tired and numb most times that I walking or standing in general when I asked my doctor about that he told me that it’s common for those symptoms because of osteoporosis but unfortunately I don’t have my doctors information right now and up to this point we still don’t know the cause of my osteoporosis I don’t want to ask my parents to take me to a doctor because I don’t want to worry them although they took me to many doctors because of my dizziness and fainting I didn’t wanna bring my suspicions up because I felt uncomfortable I hope that you can answer my question and tell me if it is possibility and I would love to tell you more about my symptoms
