blood blisters on tongue, left side

good morning everyone, lilyann here, was wondering if anyone else has had any blood blisters on their tongue. i had them the end of the month and then it seems like my mouth was ok and now it happened again. i have the aggressive papillary cancer. surgeries 2023, january and march, right side first was radical and left side second had a 1cm nodule. i am loaded with them now, all in my neck, no spreading which is wonderful. the choking feeling has not left since the biopsy in 2022 of november, like being stranguled each and everyday. wish everyone the best.
