Hi almost every day I have blood in my saliva when I wake up or even when I bend my head to pick something up.etc...and sometimes it just bleeds spontaniously..it has been going on for over 12 months now. I had antibiotics which improved the condition for about 3 weeks. I have been to the dentist and had my teeth cleaned...etc.. my doc. send me for a ENT but the specialists thought I do not need it done. It does worry me and also I don't have a cough or pain or anything. ..it does make me feel light headed.
