Feel free to disagree, but I'd challenge you to support that position with any sort of logical argument. For me, 28 years of experience as a health care professional plus simple risk management principles says otherwise. Potential harm in seeing the Doc - damned near zero. Potential harm in ignoring what could be a significant medical symptom - considerable. The OP doesn't say
why he suddenly changed his behavior, but he does site fatigue that he hadn't experienced before as a factor. The list of potential medical causes for that is so long and includes enough possibly serious conditions that only a fool would ignore it. And 'sudden onset' does not rule out anything. If anything, it only makes the arguement for medical attention even more telling.
