I started tasigna over a month ago, right after starting I got severe headaches. I went off it for one week headaches went away. Back on but slowly increasing one pill for 3 days, 2 pills etc. However everytime I get to 3 pill the headaches come back. Now back to 2 pills. However the onc wants me to go to a headache clinic. Has anyone been referred or had any experience like this. I am wondering why I would go to see a headache specialist if I know why I'm getting a headache.
