Lesions on the brain symptoms and conditions

I have been taking lisinopril for about 2 1/2 years now. About 4 weeks ago I was having trouble sleeping, my legs hurt real bad and when I would wake up I would have a numbing tingling sensation in my legs and feet. Went to the doctor asked her if it could be the meds and she said she didn't think so and to continue to take it. I still continue to have problems, tired, weak muscles, hurt and a raw lump in the throat feeling. She sent me for a brain mri that showed white lesions on the brain. She said it could be from high blood pressure but said my has never really been that high or it could be MS. I am right now waiting to see a neuro dr to see if I have ms but after reading all these post I am wondering if it is the lisinopril. Has any one else had these types of symptoms?

I was diagnosed with Optic Neuritis in my left eye, at the time of diagnosis, I felt fine. Had an MRI to check for lesions on the brain, there were none. I was put on IV solu-medrol for 3 days, then 90 mg of prednisone for one week, with a rapid taper the second week. 6 days into the prednisone, I started have shortness of breath, etc. Went to the ER and my white count was 22,000. Had bronchitis and the beginnings of pneumonia. Because of the breathing problems, I only did 2 days of taper (doctor's advice). I have lost site completely in the left eye and now I have blurred vision in my right eye. Extreme fatigue, and a mental fog I just can't explain. A "twitch" in my left left hand and muscle weakness. I just don't feel "right". How long does it take for this drug to leave your system? Has anyone had a similar experience? My eye doctor was considering another round of prednisone for the optic neuritis, but I am not so sure I can survive it.
