[|Human|] I had a full knee replacement on the 26th January and am now suffering from an itchy rash over my back and now on my shins, my Dr says this could be an allergy to the anaesthetic and now taking antihistamine tablets and applying Cetraben for the last week with some improvement, but rash persisting on leg. What do you think?
[|AI|]  Hi and thanks for the query, Its possible that it could be an allergy to an anesthesia, but the duration of the itches deserves exploration of other possibilities of the itches. A blood test in search of raised eosinophil levels to confirm an allergic component. At some point, raise Immunoglobulin E levels might be measured. A thick and thin blood films in search of parasites like microfibril should be actively searched for. A past history of recent travel to an area endemic for parasitic worms shall be of utmost importance. I suggest a good clinical evaluation by your internist and appropriate blood tests be done. Medical conditions like liver disease at times could lead to itches, Thanks and best regards, Luchuo, MD.
