I have itchy white bumps on my tongue due to an allergic reaction however now they seem to have fluid in them that taste like aspirin ?

Thrush: It is hard to say without seeing them but white spots on the tongue could be a fungal infection called thrush. It could effect your taste sensation. See your doctor for treatment.

See a dentist: I would recommend you see a dentist to have your tongue and these lesions evaluated.

See dentist: If they do not heal see a dentist or specialist in oral medicine for an evaluation.

Under care of MD?: You should be under the care of an md. There have very likely been associated changes in the taste buds of your tongue associated with bitter taste. A consultation with periodontist and/or oral medicine dentist can also be helpful.
