question: For about 5 days I ve been getting bites or hives. They show up at night when I am in bed and are pretty itchy initially, however, the itch becomes very minimal within 12 hours even though the bump remains. I think I ve eliminated bed bugs and am now trying to eliminate spiders and fleas. The only thing I can think of in my diet that has changed is blood pressure medicine. It is possible to get hives from Byhstolic (nebivolol) tablets?
