Ketamine and the day after

[Fantasian]

SWIF used about 150mg of Ketamine insufflated last night and had a most enjoyable experience. SWIF the following day felt a little groggy which he expected however SWIF had all the symptoms of a UTI.

UTI - Urinary Tract infection

ie
It hurt when SWIF urinated,
SWIF wanted to urinate and couldnt
SWIF generally felt uncomfortable in that region

However these symptoms only lasted for about 1 hour 30 minutes and after SWIF tested himself for a UTI the test came up negative.

Is it possible that the Ketamine remaining in SWIF's Urine was having an effect on the inside of his bladder and Urinary tract prior to him urinating it out.
