Is this CSF leak?

Hi, I started getting headaches about a month ago after foam rolling my neck and back. Before that, foam rolling never caused me any problems. The pain starts after sitting or standing for a while, but goes away when I lie down for some time. After lying down for a while, if I sit or stand again, I feel fine. But the pain comes back after some time.

Bending forward makes the headache much worse, but if I stay bent, the pain eases—it seems to be triggered mainly by the change in position. Pain is felt around my eyebrows, cheeks, sides of my head and back of my head. I also have poor posture, which might be contributing.

My current doctor didn’t take it seriously and just sent me to physical therapy. I’m considering changing doctors. I’ve been to a physiotherapist, but I’m still in constant pain. Could this possibly be a CSF leak? Has anyone with one experienced headaches that behave like this? It already been a month.

Thanks
