Hello and welcome to Healthcaremagic.
Thank you for writing to us.
As this is an emergency, if tru, I would like to quickly list the symptoms of a possible internal bleed, they are:
-Tenderness in abdomen, back or chest
or discoloration, especially at site of injury
-Blood in urine, stool, saliva or vomit
-Vaginal bleeding (between periods)
This is an emergency, and can result in serious complications like:
(altered mental state, confusion, weakness, shortness of breath
, pale skin, etc.)
-Drop in blood pressure (light headedness, weakness, etc.)
-Organ failure (serious symptoms)
In my opinion there could be a chance of internal injury, whether this is serious or minor (self-resolving) injury has to be elaborately checked by a doctor with the help of other non-invasive investigations.
I think it is best to visit the ER and get evaluated.
I hope you have a speedy recovery and indeed only a minor injury which can be easily resolved. If you have any further clarifications, do write back to me, and I would be happy to help you.
