'Allo ^^I wasn't exactly sure as to where this post belonged. If this is in the wrong section, I apologize in advance and so humbly ask a moderator or administrator to move it to its proper location.
I'm a 15-year-old female (almost 16), and I have a few issues that have been bothering me for a while. Earlier, I noticed that randomly my fingernails had become discoloured. It's not the first time; it's happened on numerous occasions in places such as grocery stores, in the home, outside, etc. The base of the nails are blue'ish-purple, while in the middle is a band of white, and near the top it becomes a light red. Applying pressure onto the nails discolours it to a white colour, and exerting force with my fingers onto surfaces recolours it to a dark red with a yellow-white top and a white base. My hands are usually extremely cold to touch, even in warm places. Generally, if the temperature is lower than 22°C, I feel cold, especially at the hands and feet. Sometimes it causes for shivering. Currently, my hands are cold and my fingernails are discoloured; however, it also occurs when my hands are warm, although not as often. My arms and legs have been feeling funny in the duration, too, and around the knees have become discoloured to a red with random blotches of blue'ish-purple. There are small bumps on my knees, too, that bleed after I shave around that area. My entire face is presently extremely warm, but my hands and feet are very cold. My posture is good both walking and sitting due to instrumental music classes (where good posture is mandatory). After getting out of the shower, my legs develop red areas that are itchy to touch as well and for no apparent reason. My wrists have slight pains sometimes, too. In the past, I've experienced sudden and minor papilations, and frequently need to inhale deeply. My legs move constantly while seated at the computer, and without me realizing it, they'll begin to move up and down against the floor, shaking the desk in the process. There are times where I feel light-headed and nauseous as well. Sometimes I wake up with damp hair and a wet shirt beneath the armpits due to having sweated during the night (although my room is approximately 17°C constantly (I find this freezing, although my father finds it "comfortable")).
I'm not sure if this is relevant to the fingernails, but to be safe, I've been menstruating for approximately just over 5 years, and I have no schedule. I'm currently menstruating - I started on July 10th - though the last time before was approximately May 14th. Once, I waited 6 months to menstruate again, although generally they're spaced out by 2 or 3 months. In May, I was 5'4" at 219lb and starting dieting by eating a mere 1200 calories a day (the lowest possible before the body goes into "Starvation Mode"). I am currently 5'4" and 190lb. I have not taken to any additional exercise since May. My household is one without stress and I do well at school (A+ Student, Gifted Program, Extended French, etc.). When I'm not menstruating, my vagina seems to smell bad, although I shower regularly (everyday or once every 2 days, depending on whether I've the time). There's no excess fluid or discharge that I can see; it just emits a light, foul-smelling odour that can only be smelled upon the removal of the underwear and pants, although on some occassions it can be evident just upon the removal of the pants.
I have minor hypothyroidism (I think I tested 5.7); rheumatoid arthritis inflicts my father (although I tested negative for this), and diabetes is on either side of my family, inflicting my grandfather, my sister, and my deceased grandfather on my mother's side. I have no allergies, and I am not sexually active, and never have been other than self-exploration. I am on no medications. I have minor back issues which required a chiropractor when I was 13 (the doctor would attempt to "loosen" my vertebrae by laying me out and pressing against my back to "snap" it, causing temporary loss of breath) and this issue was never fixed 100%, although I still experience random, minor pain in the middle back. My skin is, by default, unusually pale due to lack of solar exposure.
Does anyone know what could be the cause of all this? Any help would be greatly appreciated! :)
