Kathy,I also get a sharp pain,in the same place that you are talking about! However mine does increase for some reason when I bring my right knee up to my chest? The strange thing is that I have very low blood pressure? Some time's at my Dr's they can not even find my pulse? It is sure very scary when it does happen! If it does continue to really be a problem,I will have to bring it up with my Dr. Please take care of your self! Always Breezy55
