I am a 31 yr. old female, I have symptoms of various sorts for over a year. Eye pain & swelling, rt. side weakness, tingling on rt. side, now on left as well, fatigue and disoriented. My doc. ordered an MRI after ayear and it came back as 5mm lesion in white matter of left frontal lobe level of the corona radiata, and two adjacent tiny focal areas in the deep white matter of the rt. frontal lobe superiorly. Then I had spinal and it came back neg., I have an appt. with eye dr. this week. My doctor and the neuro. don't think it is MS. I have had all the blood tests done and all were neg. If I don't have MS what else could cause these symptoms? Any advice appreciated.
