I am receiving folfirinox chemo and developing clumps of blood blisters in my mouth. Some weeks I get large ones, other times they are tiny. They engorge with blood, pop, then remain as a mass of necrotic tissue. I am on blood thinners so doctors are reluctant to excise the mass. I am wondering if anyone has experienced blood blisters in mouth, and what possible triggers might be. I have a theory the big ones develop after I eat an acidic food, but don’t know if there’s any truth behind that. Also wondering how you treated them, I am treated with chlorhexidine 0.12 % mouth/throat solution, but the mass of tissue remains in my mouth. There also is some discussion on if it’s getting infected or not-I have redness on skin outside of cheek on side that has the necrotic blisters , swelling, and warmth.
Any ideas on how I can prevent them/ treat them are much appreciated. (I do not bite my cheek or eat pointy hard food) -thanks
