<s>[INST] The skin under my tongue perks and I have a taste of blood on my mouth. I have good oral hygiene. The blood taste is not my gums bleeding, it seems to be coming from my saliva. Also I have a burning sensation all over my body like a sunburn that started on my face then proceed down my neck and eventually my entire body. Been to dentists, doctors and nuerologist. Nothing they have given me helps. Any ideas what could be wronh with me? [/INST] Hello, Thanks for consulting ChatDoctorRead your query as you have blood taste on tongue this can be due to poor periodontal health causing blood in saliva and burning sensation can be due to thermal burn, food allergy, Chat Doctor.  I will suggest you to do warm saline rinses two - three times a day, you can apply ointment like stolen gum paint two - three times a day on gums, use mouthwash chlorhexidine. If symptoms persists aforementioned then consult oral surgeon for examination of oral cavity and rule out the cause of infection. Hope this will help you. </s>
