I am a 19 year old female, and have had some health complications throughout my life. When I was younger, I was constantly coming down with infections like strep, ear infections, and sinus infections. Still, my immune system seems to be just as weak, and I've been in for such minor infections many many times. More recently though, since my freshman year of highschool, I've been experiencing more worrying symptoms such as nausea, appetite fluctuation, and stomach pain (basically a slew of gastrointestinal dysfunction).
I've also had some serious fatigue, which results in me sleeping 12-16 hours per day. I could sleep for 12 hours, wake up and do my laundry, and suddenly find myself exhausted and ready to go back to sleep.
There is also pain in my body, in joints like my jaw (which pops, clicks, and gets stuck), my hands, and my back; I experience inner pain occasionally, like a dull aching and sometimes sharp pains in my chest or stomach. Rarely are they unbearable, but every so often, it is a sharp, burning pain. My limbs also tend to be shaky and weak; walking alone makes me feel as though I'm dying.
In October of last year, after going into the doctor's for nausea, my doctor realized that resting pulse seems to be very high (around 110 even when lying down) and also seems to f jump from 80 to 135 when sitting.
Other than that, I've noticed that my limbs are always cold to the touch, and can be tingly and numb often. They are very sensitive to the cold as well, and turn red; sometimes they hurt when exposed to the cold. I've also noticed some spacey-ness and dizziness, and constant dehydration.)
I looked at some of my labs, and although I didn't find what I was looking for (I remember something being wrong with my urine), I did notice that my ESR was around 25 even when my symptoms weren't nearly at their worst.
Could this be Lupus? I'm so tired of feeling like this, and my doctors aren't helping me.
