question: Hi I have had mouth problems for the last 9 weeks or so starting with a numbness on one side of my face,tingling sensation and burning of half of my top lip on the same side of the numbness, I later found mouth sores or ulcers and the roof / palet of my mouth felt spongy and unpleasant again on the one side I have had to take pain killers and mouth wash every few hours for the first 3 or 4 weeks.The pain has now gone and the numbness reduced but still present.My palet seems better and I am not in any pain.23 years ago I had a cancerous tumour ( a lymphoma) behind my left eye. This was succesfully treated with radio therapy but leaves me more anxious that this vould be cancer.I have seen the dentist had an ex ray and no problems with my dentistry.I have been to the hospital had blood test and biopsy of ulcer. Both showed no adnormalities.The ct scan showed something possible suggestion of synositus but this is on the opposite side of my face.I have just had an MRI scan and waiting for results.Could this be cancer and can it be treated.Do you have any thoughts or experience of anything else it could be
