4-5 weeks ago I slipped, caught myself with my left hand/arm/shoulder. I had a big bruise on my shoulder. It partially went away. But now there is still have a funky bruise left ... and sometimes, in certain positions, my left left thumb and index finger go numb - fall asleep .
Hello, The bruise in the shoulder suggests a local injury and some internal bleeding. The numbness can be due to mild swelling around the nerve roots. A direct examination is needed for proper diagnosis.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
