Hi, your symptoms can be related to excess of coffee intake. When there is a high caffeine
in the body it may lead to profuse sweating, anxiety, restlessness, increased urination, increase blood pressure and heart rate, nausea, stomach ache, cold sweats, irritability etc. Hence, you need avoid coffee. Better to practice regular exercise with diet control.Hives seems to be independent of coffee intake and can be due to secondary to exposure to allergen and mediated by IgE antibodies.
