Re: Numb Fingers after Broken Collar Bone
Might be a problem with your ulnar nerve or a nerve problem directly related to the collarbone injury, like a thoracic outlet syndrome. (some form of TOS is common after motor vehicle accidents where there's upper body injury)
There are various treatments for both conditions; anti-inflammatory medication, splints, physical therapy, surgery, etc. But it all depends of your individual condition and situation. See your orthopedist.
