Yesterday around 2pm when I stood up there was intense sharp painful headache and alot of pressure. I thought i would faint from the pain and had to grab my head and squeeze and sit right back down. I have never had headaches so this is weird for me. It has now been 24 hours and I still cannot stand, lie down completely, walk, or even turn my head without another one of these sudden headaches. It's so painful and makes me feel drained immediately after like I could faint. I don't have any kind of cold or runny nose or congestion so I don't think its sinuses. And no sensitivity to light so maybe not a migrane. And it only lasts for 30 seconds to a minute until I move again at least. I called my doctor but he is on call and I am waiting for my call back. I tried to google self diagnose but came up empty handed. Anyone ever had this happen to them and could tell me what is going on!! I haven't even slept because I'll turn my head or lay down further and the pain comes and wakes me up. Now I just feel like crying because it hurts and I'm tired and I don't know what wrong. Thanks ladies for any help!!
