I am 34 year old male with a right brain AVM, located beside my motor strip, that was found incidentally. Before Gamma Knife I didn’t have seizures or headaches. However, since Gamma, 8 months ago, I have been diagnosed with possible simple partial seizures. I get an odd numbish-tingling feeling that starts on my left back/shoulder and moves into my upper left thigh and arm. Recently I have started having them more often. In previous months I had roughly one of these a week to every two weeks. Now they are happening almost daily. They last about 7 min on average. You wouldn’t know it was happening unless I told you. I can still move freely and speak eloquently while they are occurring. Has anyone else experienced this as well?
