One of my most distressing symptoms of CFS for me is the tension headache that never really goes away. Another friend recovering from CFS recently mentioned her similar headache, and since I’ve got one right now and I’m in a bad mood, I feel like complaining a bit about it.
Back when I was a computer engineer, I used to get regular migraine-intensity headaches about once a month or so. I would spend hours every day engrossed in a computer screen and often felt a headache coming on in the afternoon. I was so obsessed with my work that I would just push through until the pain was so debilitating that I would need strong painkillers with codeine just to get through the day. Once I got to sleep I would be OK the next day, but if the pain was too intense to get to sleep, it would often escalate until the pain was so excruciating that I would be nauseous and vomit. Vomiting with a migraine was a horrible experience but would usually give me some relief, and then eventually I’d fall asleep.
The next day, I’d feel really groggy but the pain would mostly be gone and I’d be back to work. The day after that it felt like nothing had happened and I’d be back to go go go mode. Then a few weeks later I’d do it all again.
