hi again everyone,
i haven't visited for a while so first i will answer oritil who asked what kind of infection i had in the end. i don't know but i still have the prescription bottle. i took Clindamycin HCL 300 mg for ten days. the lump almost completed deflated very quickly and now, in january, there is only the tiniest lump that i guess is a bit of a scar.
maryam, for sure go check your tongue with an ENT specialist as soon as possible. be sure he considers the option that it's an infection. also, i first was given weak antibiotics that had no effect on my lump. the second stronger round did the trick. good luck. i hope you are fortunate and also discover that your strange lump is just an infection!
all the best to everyone here!
