Toprol-XL and searching the internet

I have been on generic Toprol since 2005 to control my high blood pressure. I have many of the symptoms you all experience, tiredness, occasional dizziness, some weight gain. However, the most debilitating side effect I am suffering is neck flushing and anxiety attacks, my chest and neck turn bright red practically whenever people talk to me and I've never had this problem prior to taking this drug, I am shy but not that shy. Now I feel like I have to wear turtlenecks all the time or people will ask me what is wrong with you, are you allergic, etc... I can't even have a regular conversation with my co-workers without my neck turning red and breathing hard. It's ridiculous and I want to know if anyone else has this problem or if I'm just mental.

Thanks.
