Every evening I have this strange feeling in my head. It's hard to describe. It's like pressure, but också feels like you are about to faint. Nausea.. Tinnitis becomes louder. I am taking the same amount of Stalevo I have taken for a couple of years. Idon't think it's an"off" time. I have problems with my blood pressure, up and down like a jojo. I have taken BP when I feel this way, it's not exceptionally high. Has anyone suffered the same problem or has any ideas of what it could be due to. Gratefull for any tips.
