[|Human|] Hi, I just discovered a hard pea-sized lump at the base of my skull on the right side. I have had 2 brain surgeries--one for a brain tumor and the other for trigeminal neuralgia. In the last month or so I have had some numbness and then tingling on the right side of my face and sometimes the numbness has lasted a while. This is the side of the trigeminal neuralgia. What is your recommendation?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. Your tingling and numbness may be due to trigeminal neuralgia.  Your lump has no relation with that.  Your lump may be enlarged lymph node or soft tissue tumor or cyst.  Consult your doctor and go for examination.  If needed go for biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
