I have no idea what is going on within my body. Everyday seems different. One day I'm in no pain at all and the next is like a train hit me. I've been ruling out disorders and diseases that causes pains everywhere. I do not have extreme flexibility in my joints but have soft like velvet and firm skin. In fact, they are strong. My joints hurt so much for no good reason. I'm tired of this and trying to find a doctor or have my mother to understand me. I'm 17 years old right now. I've been diagnosed with POTS, NCS, IBS, MDD, anxiety and trying to fight what's not diagnosed. I'm not in my depressive episodes that causes "pain" in my body like my counselor and children's psychiatrist told me. I'm in my better moods, and the pain hasn't gone away. I've been having tachycardia issues (140 while sitting and doing nothing) which kept me out of school. My chest pains are sharp but recurring off and on. An echo showed I have a slightly larger aorta artery for my height (5ft 1in). My fingers aren't long and weird I not are my toes. They are normal for my tiny figure. My muscles and joints never stops. I have strong fatigue that limits my day. 20 minutes worth of clothes shopping flares up my legs and arms and neck plus my back like crazy... I'm nearsighted and wear strong glasses. My vision started going blurry in second grade maybe even before. My vision is worse and worse from last year. I change four clicks (I know there's no real unit for the eye sight machine) this year from my vision last year. My concentration is poor. My memory is crap. My motor skills are a little off. I'm tired of this. I'm tired of being exhausted and in pain all the time no matter what my activities are. What should I do? What's putting me through this awful pain? How do I get my doctor's attention on this? How do I explain this to my mom? She's 57 and conceived me at 40. She's old and says I'm not in real pain.
