Intense heat symptoms and conditions

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.

I've taken 500 mg of Levaquin for 13 days; cut back to 250 mg. Joint pain started about 7 days after start. Gotten so bad, have difficulty walking. First side effects consisted of short term (hours) of rash, intense heat, itching. The pain has gone from knees and elbows to fingers and ankles. Also brusing in legs. Suppose to be on for 7 more days, but have called the doc and told him I'm done with this. I took this med last year for a urinary trac infection and had to get off it then. Told the doc this but he didn't listen. Next time I listen to myself.
