<s>[INST] Hi, I have been having some lower tooth ache (front teeth) accompanied with slight numbness in the chin and lower lip. Last night I had tremendous pain in my lower teeth, all accross the lower jaw this time that i was forced to take pain killers, this morning my chin and lip is completely numb / dead. There was some blood on my pillow a few nights ago and I am extremely tired / fatigued of late. I did some research this morning and came accross information that made me worry abit - "Tooth Pain and Numb Chin as the Initial Presentation of Sytematic Malignancy".....should I be concerned?? [/INST] Hello,Thanks for writing to us.Cause of toothache as well as numbness has to evaluated and treated accordingly.X-ray investigation will help to evaluate the cause of toothache.Root canal treatment as well as deep scaling has to be done.Take dolo-tabs as per prescription.Take care. </s>
