Treatments for minor head bumps or hematomas include applying ice to the area and keeping the hematoma elevated, says RX List. Generally speaking, hematomas clear up on their own and do not need treatment. When medical attention is required, it takes the form of surgical drainage.
Surgical intervention is potentially called for when the head hematoma is accompanied by headache, generalized weakness or confused thoughts. Hematomas occur when blood collects outside of veins or arteries. This typically results with blood vessels are injured, which causes gradual seepage into outside tissues. Among the most serious hematomas, subdural hematomas are seen between the skull and the brain, according to RX List.
