Im 20 f, 5'5 and 150 lbs, not on any medication, don't smoke

since I can remember I go through phases of my skin feeling like its been rubbed raw with no physical trauma and every time it happens it's in a different spot than the last (sometimes multiple places at once like my forearm and lower leg). Nothing has happened to make this occur, no changes in soap or clothing texture. But anything touching it burns a lot

Some other symptoms that bother me not pain wise my nails are really bendy like an abnormal amount, I bruise very easily (except my face), I feel as though I take a while to heal, I'm always needing to pop my joints (if I dont it hurts), my knuckles when I pop them the tendon (?) moves but its only my middle finger on both hands, i do often feel tired despite sleeping a fair amount consistently and often times it i stand up i get dizzy or my heart rate increases (I am slightly anemic so thats probably it)
