Hi and thank you so much for this query.
I am so sorry to hear about this bruise
and the pain you and. I will say do not get too worried about this knot. Try some pain medications for this and let's see what happens within 3-5days. If symptoms should persist or get worse, then you may consider returning to see your treating doctor,Hernia
are generally diagnosed by talking to the patient and examining. a test is rarely needed. And with a CT scan
done in this case, it would have be a very rare miss not to pick up a hernia if there was any. I am sure it cannot be a hernia unless it just happened suddenly which is unlikely.
I hope you find this helpful. Thank you for using our services and please feel free to ask for more information if need be. I wish you the best of health.
Dr. Ivo, MD.
