This has come on in the last week or so. I've been waking up fine in the morning but feeling a bit tireder than usual. Over the day the tiredness gets worse until mid afternoon when I can hardly hold my head up (literally). The headaches start around lunchtime and get progressively worse. I feel a bit better after tea but still not right. Then the next morning it starts all over again. The headaches feel a bit like the precursor to migraines and I get sensitive to smells and light but it rarely progresses. If I sit still I feel better but when I get up or move it starts stabbing again. On top of that I'm going to the loo really frequently. Any ideas please?
