One year na ako dito sa southern china na ngayon eh sobrang lamig (walang snow kasi 7 to 15 deg C lang naman pero malamig pa din). Pag kunyare malamig sa labas tapos nag-hot shower ako, nalalasahan ko yung blood sa mouth ko and when i spit, i see a mixture of blood and saliva. Mga 1 or 2 spits lang makikita yung presence of blood in my saliva, after that wala na, so I just continue taking a shower. So bale yung first few seconds lang when i start taking a shower lumalabas yung symptoms.
I sought help na with an ENT here where the doctor put a narrow tube with a camera through my nose and took a picture of my throat. wala naman daw problema kaya di na ako binigyan ng medicine. Then I also went to an internist and got a chest x-ray. Pareho lang din, wala daw problema.
Akala ko dati pag malamig lang nangyayari to kaso umuwi ako recently sa pinas tapos nung mag-shower ako (tap water so room temperature lang yung tubig pero mainit sa labas), I tasted blood again. Hindi naman talaga everyday to nangyayari so I really have no idea what's triggering this. I also don't feel anything wrong with my body - no ulcer, no pain anywhere, everything feels normal.
My friends told me to just ignore it, maybe it's similar to nose bleeding daw pag malamig ang panahon, except the blood comes out through my mouth. But then spitting blood isn't normal, right? So any ideas?
