Headaches post surgery

Has anybody had occipital nerve blocks for headaches? I’m just wondering how well they work…

I had them both pre and post op, with the most recent last week. I am 2 yrs post op. I am not sure what type of headache you have. My HA stem from the sub occipital area and then radiate. I have tried several alternatives but found most relief from these blocks. They also added a steroid this past time which aided in the inflammation. Hope this helps!
