[|Human|] I have been smelling an offensive smell in my nose for a few months now intermittently and had a numbness at the base of my back, now a strong pain in my right buttock.  Could the 2 be connected?  Im always tired and just put it down to the change in weather, always being cold and dark
[|AI|]  Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms (intermittent bed smell)are really complex and could be related to different causes like an infection of the upper airways, epilepsy or a tumor of the base of the scull. Anyway, it is less likely that the bad smell and low back numbness are connected to each other. For this reason, I would recommend consulting with your doctor for a careful physical examination and performing some tests to investigate for the possible causes: - a sinus X-Ray study for sinusitis- a lumbar spine X-ray study-complete blood count, ESR, PCR for inflammation or infection. A brain CT scan may be needed to exclude a tumor of the base of the scull, which may lead to your symptoms. An EEG is also needed to exclude seizures. Hope you will find this answer helpful! Kind regards,
