I?m a healthy 24 year old male with no diagnosed diseases but the problem with my condition is that every time when I flex my lateral side of the right sole during sudden walking or running, my right side of the face, mouth, right shoulder and arm involuntarily starts cramping for few seconds and then I get back to normal. There?s no other symptoms like falling or feeling nauseous. Also it does?t happen all the time. I?m an athlete and I do sports so this condition does?t limit my motor ability, but when it happens for few seconds in rare occasions it does?t feel normal. I have been aware of my condition since I was a young boy but there are no other explanations. I went to the neurologist over 10 years ago and had a brainscan and other tests but even specialists could?t find anything. According to the tests I was normal but my condition remained unknown. My mother told me she had a similar condition on her teenage years but she hasn?t come to her since. I?ve gone through almost every medical book to find about my condition but nothing was ever found. I hope maybe you could have your own analysis according to my symptoms.
