I started out with typical cold symptoms, congestion, cough, slight sore throat. Thought it was getting better, because the sore throat went away and started coughing up phlem, clear. Today I started to get this severe itch behind my ears and on my arms and hands. Thought it may be an allergy or something, took Benedryl, eased somewhat but woke up with my muscles in my arms and hands hurting deep down.
