After my daughter's 2nd concussion in 7weeks from soccer, she is experiencing weakness and numbness in her right side. 4 days after the accident, she is unable to walk without a limp, claiming she feels pins and needles from her butt cheek to her ankle. Her lower arm and hand seem to go numb on and off ... she describes it as hitting her funny bone. Her foot seems to be fine. Her CAT scans and MRI were negative and her condition has stumped the doctors, we are waiting to see a Neurologists but it is hard to get an appointment. Any ideas?
