[|Human|] I woke up at 4 in the morning unable to sleep because my body is so itchy. I m most itchy all over my calves, behind my knees, my stomach and the inside of my elbows and the rest of my body is still itchy, just not as much. There is no rash . I haven t eaten or done anything I don t usually do. I m 14 years old. I see I m taking skin off every time I scratch . I put lotion on my legs but that made them itchier. My skin has been a bit itchy before, in a specific area, but never half this bad. I took amoxicillin for ten days about 3 months ago. I don t have any allergies that I know of.
[|AI|]  Hello, The condition you are describing may be urticaria which is itchy red lumps and bumps on the skin with sometimes swelling of lips and tongue. It is due to histamine release from mast cells that can be triggered by infections or sometimes idiopathic. The condition resolves on its own and antihistamines help in lessening the symptoms. Do NOT scratch as physical urticaria is one entity that worsens on scratching. Full blood count (to exclude infections), liver function & thyroid function check is sometimes helpful. Long-acting non-sedating antihistamines over 6 weeks to 3 months (if 6 weeks is not enough) such as Allegra (Fexofenadine) 180 mg/90 mg and/or cetirizine 10 mg at night is recommended.
