Hello I have recently been diagnosed with cluster headaches. Although I’ve had these headaches for years they’ve never been frequent enough or severe enough to make me go to the dr. I’ve had multiple attacks every day for over 2 weeks now. Mri mra cat scan all normal. Neurologist prescribed my emgality and sumatriptan injections. The sumatriptan works fantastic but I’m getting 2 attacks per day on average. The script only gave me 6 doses and cannot refill for 25 days. Why is this? And is there a way around it. Thank you for any input. -Matt
