[|Human|] Hello. My son began having itchy hives on his shoulder two days ago. They increased surface area early last night to include his entire upper body (above waist). By morning the itchiness has decreased. Negative for other symptoms other than slightly swollen lymphnodes in neck. Do you think this might be viral and will just go away on its own. Negative for fever. Thank you
[|AI|]  Hi, According to me, you might be suffering from Acute urticaria (hives). It resolves completely if you find and avoid the cause of urticaria and take antihistamine tablet for a week.  Most common causes are food, Chat Doctor.  You can take an antihistamine tablet for a week.  If your symptoms do not improve in a week or if you have any other symptoms, you should consult your Dermatologist for further management. Hope I have answered your query. Let me know if I can assist you further. Take care
