Hi. I Am A 16-year-old Female And Was Just Diagnosed

Hi. I am a 16-year-old female and was just diagnosed with POTS. I have not been able to attend school or function due to it, but midodrine has luckily relieved some of my symptoms for 12 hours/day so that I can live relatively normally during that time period. However, I've also been experiencing debilitating joint pain for a while. I have always experienced some degree of joint pain, but it didn't disrupt my life until now. I also have extremely hypermobile joints (as does my mother, who has experienced pain in the past from them), and a family friend who has Ehlers-Danlos as well as POTS was wondering if I have EDS as my mom and I both show nearly all the symptoms of the hyper mobility type. I'm seeing my GP on Wednesday to address the pain, but I'm very nervous about the whole thing. I'm really hoping that it isn't EDS (obviously), but do you think it is a possibility? I may be just being paranoid and freaked out as any young person in my situation would be, and I realize I am not your patient and you cannot diagnose me with anything. However, could it possibly be EDS? Am I right to suspect this? I'm not usually the type of person to "diagnose myself" and typically do not consult a doctor unless it is serious.
