Noticed A Large Dark Bruise On Inner Thigh And Back Of Thigh Above Knee After Hit. Concerned
Thanks for posting your query.
You must have got injured internally. The bruise which you notice seems to be a haematoma (internal bleeding) that's usually caused by rupture of some blood vessel in thigh. Usually these swelling are self limiting and will regress in a couple of days. You might notice change in its colour when it heals, from red to blue and finally pale to normal skin colour.
Haematoma's are very painful. You can consult your family physician or orthopaedician and depending upon its size and severity they can decide to either excise it surgically or allow it to regress on its own. The only precaution that you must keep in mind is that it should not get infected (from any other source in body), cause if it does it will turn into an abscess.
In my opinion, take a hot fomentation with douche bag twice a day, have absolute bed rest, take sonography to diagnose the root of trouble.
Hope this answers your query. I will be glad to answer the follow up queries that you have.
Please accept my answer in case you do not have further queries.
Wishing you good health.
