I get muscle twitching all over body for over year. brain mri showed lesions on frontal lobe not pathological. do all lesions mean ms?

Lesions: Rarely do brain lesions cause muscle twitching. There are are many causes of brain MRI lesions. Some causes are benign/nonpathological (falsely termed) due to not portending a specific progressive/degenerative process such as gliosis/lesions seen in migraine patients. Some lesions are definitely pathological like in MS. But diagnosis is clinical - based on history of symptoms, MRI, LP, & bloodwork
