Hi
Thanks for posting your query on HCM.
I appreciate your concerns following an unexpected trauma due to fall.
Well, as evident from your history it appears that you do not have any problem with your breathing, urine, bowel habits (although it is said that you attend the nature's call once in two days, that may be normal for you).
There is a strong possibility of muscle sprain that could have developed due to fall on your left side between the pelvis and the ribs.
Regarding the side effects of Advil (Ibuprofen), it is an effective NSAID drug used to treat various painful conditions including the
muscle pain due to sprain.
Its use is associated with acidity related
stomach upset, heartburn, bloating sensation and development of
allergic rash in susceptible individuals.
These side effects can be minimized by taking Advial in presence of a drug like
Omeprazole or
Ranitidine.
Hope you are convinced by the explanation given above.
Wishing you best of your health.
