Does anyone have experience of cluster headaches? My DP had a sudden throbbing pain behind his eye and around his temple at the start of the week. It comes and goes through the day and night. Went to GP who diagnosed cluster headaches and he’s taking codeine/paracetamol and ibuprofen which he says is helping a bit. His eye looks very red and weepy, and the area around his eye is very swollen. He says the pain is dull and throbbing, but from what I have read about cluster headaches the pain seems extreme and unbearable. Can cluster headaches be mild? He has no appetite and has pretty much been horizontal since it started. How long do these episodes last for typically? He is never ever ill, so it’s a little worrying to see him like this.
