Suggest Treatment For Red And Brown Spots On Body

After taking amlodipine 5mg, I will feel warm and fushing, my upper elbow and area around my knee will have red and brown spots, after around 3 or 4 hours my eyes felt puffy and watery, my mouth will be dry as well. I go to the gym 3 times a week and usually during and after exercise the red spots will aggravate more and also it will extend to the back of my body. The red/brown spots are not raised and not itchy. Some of this red/brown spots will go away after 24 hours but some remain. I will get the same symptoms if I drink alcohol.
