My husband is on antibiotics for an infected bug bite but has some strange symptoms, loss of appetite, nausea; I can associate with drug but his right leg feels cold and clammy and his primary complaint is discomfort in lower right abdomen. He is sometimes breaking out in sweat and sleeping a lot and when not sleeping finds it difficult to sit still, reminds me of a woman in labor. Constantly walking and changing position. He is 73, has high blood pressure, lately in high 170's and is overweight. He is not a complainer but I am worried. Should we be at the emergency room?
