### input:
Sudden itchy bump on right hand while at work. Next day woke up with another bump right next to it. Over the course of a few days, new bumps will randomly appear on my arms, neck, lower back. And today, they have appesred on my shins. They are either single bumps, or maybe two or three in a straight line. Very tiny and clear. Once one bump goes away, it seems like a new bump appears elsewhere. No changes in diet, detergents, hygiene products, ect. Although we do use wood heat, but this has never been a problem before. Took cipro for uti a month ago. Currently take one 50mg tramadol a day(since 2008). I work at a hospital and was afraid i contacted scabies . Spoke with er doctor who said it is in no way scabies, but looks like some sort of bug bite or allegy. Was prescribed lindane , but will not use it! When these bumps appear, it is very sudden. With a sting/intense itch sensation. Itching will last a few moments, then fade for a few hours to days. No bed bugs or other insects that i am aware of are present.

### output:

Hello, Scabies is very unlikely and the symptoms you describe are against scabies and therefore no need for lineage. This is acute urticaria and occurs due to histamine release that is occasionally triggered by infections such as UTI, pneumonia etc. and (also scabies incidentally) but the histamine continues even after the treatment for the infection is completed. The UTI may have triggered the urticaria in your case and am not sure why you need the tramadol. Opiate analgesics can worsen urticaria control, so please ensure this is not the case. Long-acting nonsedating antihistamines for 3 months is the treatment and up to twice daily is standard treatment.80% of urticaria is non-allergic. Thanks.
