I've experienced this problems for about 8 months now, when i'm sitting or standing naturally, like, not forcing myself to have a good posture, i'm all fine, but soon after i decide to stand with my back straight and my shoulders back and my hands down, i feel numbness in my right arm and hand, and it gets worse and worse unless i go back to my normal posture. ( the posture which i want to improve, but this problem doesn't let me to). i also feel a kind of pain in the elbow area, just the inside part, (i dont know what's it called sorry) and in addition, my right hand becomes blue, and when i compere it with me left hand, there's a huge difference in color. The reason i'm posting this in scoliosis section is that i have an S shape scoliosis and my doctor associated my problem with either that, or that i have unstable neck segment. i started doing the exercises for scoliosis + neck stretches, the instructor told me my problem would go away after 3 days of exercising. i finished 1 month course and no result. i was advised to start swimming, which i did. not sure if it helps anything. Can you come up with any different causes or treatments, and what if i'm not able to treat this problem? will it lead to anything more serious ?
I'm 16, if you need to know.
