I have ankylosing spondylitis and I am on Enbrel. Last Feb. I had chest pain it felt like pleurosy. I have had it before, Cest xray normal so they treated me for reflux. it did not help so they ordered a stress test (family history).I had a heart cath. for abnormal stress test. Could not walk well, out of breath weak stutter and developed a tremor. The ER said it was vertigo and orthostatic hypotension because they could not find my blood pressure. I went to a neurologist a couple of months later and she said it was a stroke based on a clinical diagnosis. First MRI showed one 5mm white matter lesion. Second MRI showed nothing and the lesion was gone. I went for a second opinion (now a year later before I could get in). I still have the fatigue, numbness in both feet, tremor kinetic and resting combo. , stutter when tired, loss of balance , my legs give out on me left more than right, left leg swelling.( the Er said the swelling was because I was 50, wear and tear) feel faint at times. My emg today was normal, blood tests are normal, and I was told they will watch the symptoms for a couple months. I have been watching them for a year. New Neuro does not think I ever had a stroke. I am thinking maybe I should just stop taking the Enbrel and try to deal with it. It sounds like ms symptoms to me. Any one have an idea?
