Welcome to Health Care Magic. Thank you for posting your query.
I can understand your concern.
The exact source of acute
low back pain is often difficult to identify. In fact, there are numerous possible pain producers including muscles, soft
connective tissue, ligaments, joint capsules and cartilage, and blood vessels. These tissues may be pulled, strained, stretched or sprained. Enough of information.
Since you fell down a few days ago, probably there is a sprain or something like that.
Continue to apply the
heating pad twice a day.
I would suggest you to take a combination tablet consisting of Flupirtine Maleate and
Paracetamol. Do not forget to take a H2 blocker like
ranitidine along with it.
No need of any investigation as of now.
I would also suggest you to visit an orthopedician. He/she can examine you and correlate clinically and guide you on the further steps.
Hope this helps.
Post any other question. We will be happy to help.
Have a nice day. Thank you.
