Could antibiotics (Cefprozil) trigger weird pains and allergies?

Hi. I don't know what to do now. I've been having abdominal pain for 4 days now? I started taking Cefprozil for a suspected ear infection and was on it for 4 days. Then, I had sharp pains in my lower left abdomin. I stopped immediately taking the drug. Now, my whole stomach area hurts, I'm very nauseous, my back, neck and shoulder blades hurt, too. Could this all befrom the drug? I don't know if I should go to the Emergency Room or not. Advice anyone??? Thanks!

Many members have reacted to antibiotics, and there doesn't seem to be one in particular to avoid except the fluoroquinolones so I'm not sure if anyone has mentioned Cefprozil.  You can do a search using this search tool, its better than the forum search function in case no one responds.  http://www.benzobuddies.org/forum/index.php?topic=251991.0
