Vi-Q-Tuss and allergic reaction

Anyone else have shoulder pain and/or rib pain? Almost like a gall bladder attack? Have taken it twice and both times have had a severe pain for a short time, helps cough though..Is this just me or a common side effect? Also the itchiness..

Its like drinking a shot of weak schnapps. Doesnt really alleviate the cough or make anything cough up easier, but it does mellow you out. No nausea, no dizzyness. I think the people that had those problems maybe had an allergic reaction.
