I've been having some strange symptoms that are beginning to worry me. Occasionally, while I am doing something (such as shaving or cleaning), I get stuck, like a mental block, and cannot continue what I am doing. It is not that I forget what I was doing, but I suddenly cannot remember how to do it. I can identify the object (such as a razor or sponge, etc) but I can no longer remember what I need to do to accomplish the task. This lasts between a few minutes and an hour and then as suddenly as it started it stops and I can resume whatever I was doing. The first couple times it happened I ignored it and went about my life, but it seems to be increasing in frequency. The first few occasions were months apart and now I've had 2 occurances within 4 weeks. This has been going on around a year and a half.
I do not lead a stressful life and I have not been able to determine any similiar circumstances between these occurances. They do not appear, to me at least, to be anxiety or emotionally related. I also am having headaches that are increasing in frequency and intensity (although they do not necessarily occur when I am having a mental block).
