Hello and welcome to HCM.
Thank you for your query.
It appears as though there could be a possible serious infection that could be causing the neck stiffness
and pain. This could also be due to other reasons like: trauma, arthritis
, narrowing of the spinal canal
, but can also be due to an infection which is a considered serious due to your location.
I express concern as you have another underlying condition (a UTI), which could be the primary cause or secondary. Please do not discontinue the antibiotics, as antibiotic coverage is primary here.
Although you might require a more potent and high-grade antibiotic if you have been diagnosed with another infection of the neck or head region. I would also request you to kindly get a blood and urine culture and sensitivity examination done, which would provide us with a lot of crucial information.
Please do not delay any further and report to your doctor of the emergency department at the earliest.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
