Good afternoon , about a week ago I tripped while walking And took a pretty hard fall ... I bruised both shins And my left shin has a bump that  is numb when I touch it . However when I rub against something or sit with leg under The pain is excruchiating . I dont know if I should see a doctorOr not .
Hello and welcome to Chat Doctor, Trauma usually leads to hematoma formation or blood collection.The hematoma usually resorts after a couple of days. Formation of a swelling after trauma which is numb suggests nerve injury. Nerve injury can lead to altered sensations or decreased sensations. Associated pain is again suggestive of nerve injury because nerve injury can also lead to pain. A clinical assessment of the painful lump is required to diagnose the condition. I would suggest you to consult an orthopedic for clinical assessment. Thanks and take care Chat Doctor.
