Thank you for your query at DoctorSpring.com
I also apologise to you, for the exceptional delay in reply.
From your description it seems more of a muscle pull, since you participated in active sports recently.
Adequate rest, local anti inflammatory spray ( for instance volini spray ) and Tab. Advil twice a day will be helpful.
I will advise you to rest your back as much as possible and Tab. Advil for 3 days.
In case it does not resolve, you can get an X- RAY done. As of now i is not required.
Feel free to discuss further,
Patient replied :
Are there any substitute for the spray as I am afraid I cannot find it in Singapore. And I am allergic to NSAIDS too, any other alternatives for the medication? And I am not sure how does a muscle pull feels like, but it seems like it cause pain over a wide area while mine is localised around the spine rather than across the whole of my lower back. And could it be a sprain? When will I require medical attention?
Thank you for the follow up.
In that case i am not sure what is locally available in Singapore, however if you request the pharmacist he will be able to guide you ( Relispray/ Volini ). I suggested volini spray since it is by ranbaxy and should be available globally. However any muscle relaxant spray will do.
Since you're allergic to NSAIDs i won't recommend using any of the painkillers.
You can take Tab. Chlorzoxazone 500 mg, twice daily, it is a good drug for muscle spasms.
Since it is localised it favors more in favor of muscle spasms.
Try this medication for 3-5 days. In case there is no relief, you can get an X-RAY done of your lower back and upload the reports.
Based on that i can guide you further,
