Journey27,
Were you told, and following any follow-up care and or medication? I recall my tongue biopsies to be painful as the tongue has many nerves, and bleeds more too. I would mention all this to your doctor on Wednesday or see if they can move your up your visit to Monday or request meds to cover you til then, and any follow-up care. If it gets worse or continues, you can always go to the ER.
Not sure if this helps?
