10 Causes of Trigeminal Neuralgia
Cause #3: Tumor
A tumor is a mass of abnormal growth of tissue. It can refer to a solid or fluid filled cyst. Examples of tumors that may cause trigeminal neuralgia include a meningioma or arachnoid cyst. The compression of the nerve from the tumor may injure the protective myelin sheath of it resulting in hyperactive and erratic functioning.
This means slight stimulation of the area supplied by the nerve may result in pain. It may also hinder the ability of the nerve to stop transmitting pain signals even after the stimulation has ended.
