hi, im a 28 year old female. i was in hospital almost 3 months ago with palpitations, diagnosed as inappropriate sinus tachycardia as no other symptoms present. since then i have developed a dry mouth (not diabetic), headaches on most morning, calm down but don t disappear, sometime with a stiff neck on one side. i have had bruises come up on my body a long with petechiae (on back and hand). i had blood tests done for coagulations and it came back that everything is normal apart from the aptt (ptt). im hungry a lot, but dont eat as i feel sick. i feel very low and mayb tired more than usual. i have had a few more fevers than usual, lasting 24hours max, once every 2/3 weeks. i have on most occasions have had blood in my urine (not sure if it is from the kidney stone i had 5 years ago that passes a year later and may have caused damage?) as far as ive read, petechiae isnt a cause of blood clotting problem but more a sing of things like scurvy or lupus ect. is there any chance from the sympotoms you have read i copuld have something as serious as these illnesses.
