I am 34 years old and married and have had this problem for about 3 years already. I'm pretty sure it all started when I experienced some stress at work (no longer have stress) for about a month about 3 years ago. In a matter of weeks I started experiencing ED, fatigue, headaches and muscle weakness. These symptoms are always with me and seem to come and go in cycles of about 1 or 2 weeks (1 week bad, 1 week better). Sometimes my symptoms are better than other days. That's the weird thing about this. Whenever I think I'm getting better I start to get worse again and in a couple of weeks a little better and the cycle repeats.
Now I've been to doctors ranging from endocronologists, acupuncturists, naturopaths, urologists and had countless blood tests for testosterone, viruses, anemia etc. Everything was normal. These symptoms usually don't stop me from working and haven't gotten worse but it has greatly affected my life. In addition to ED, I also experience increased fatigue after any kind of exercise (so I don't exercise anymore). I have headaches some days (maybe 20%) but not all, and fatigue. I've been prescribed Viagra and it has worked a few times but I don't really want to take it anymore. I want to find what's causing me to feel this way. I don't think it's psychological ED since I haven't had a full morning erection in 3 years, I used to get them at least 50% of the time. I'm just at a loss already. Before I was active both sexually and physically. Now it seems my zest for life is zapped. It would even encourage me if someone else said they were experiencing what I have, just to know that I'm not alone in this struggle. I really have no idea what's wrong with me.
