I have these feelings come and go. On the left side of my neck I get this twitching feeling. Just below my jaw. My right shoulder/arm gets a loss of feeling. I wonder if it's seizure related. I have been told I need to see a shoulder surgeon about my shoulder and arm. About 15 years ago I did have surgery on my right shoulder cause I tore the rotator cuff. They also said I have a pinched nerve in my shoulder. About 12 years I was in the hospital cause I had a stroke. Could any of this cause those strange feelings. I have also had surgery done to my right knee. I might need surgery the second time. It just feels strange when you can't feel your right side. Could any of what I been feeling be warning signs of anything serious?
