Thanks for posting your query
It seems you have developed muscle strain
over lower back following sneezing
, due sudden jerk and pressure. To reduce pain and for better healing-
Do hot fomatation at site
Apply musle relaxant gel 2-3 times a day
Take antiinflammatory drug like ibuprofen
to reduce pain and inflammation.
Avoid forward bending and heavy weight lifting. And rest well.
Hope this will helps you
