From the National Institute of Health's Library: The following symptoms suggest a more serious head injury -- other than a concussion or contusion -- and require emergency medical treatment: - Changes in, or unequal size of pupils
- Convulsions
- Distorted features of the face
- Fluid draining from nose, mouth, or ears (may be clear or bloody)
- Fracture in the skull or face, bruising of the face, swelling at the site of the injury, or scalp wound
- Impaired hearing, smell, taste, or vision
- Inability to move one or more limbs
- Irritability (especially in children), personality changes, or unusual behavior
- Loss of consciousness, confusion, or drowsiness
- Low breathing rate or drop in blood pressure
It doesn't explain whys, though. Still scanning... Ugh. Ok, anecdotal then. Assuming that you don't have a brain 'leak', what a concussion can sometimes do is alter your chemistry. Some types of signal transmitters traveling through your blood can lower the pressure. Just like adrenaline raises it. There are numerous ways this can happen. All kinds of things tell your body to slow down, or calm down, or open up capillaries, or pool blood in a certain location... Oxytocin's one example out of many. Or something could have knocked loose potassium from somewhere. Or you could be eating more potassium. Or less salt. a.k.a, pre-existing condition masked by the knockout. Those are some possibilites. The least likely is that you're bleeding internally, and I think one of your posts said they checked you out alright? If not though get checked NOW, as of course you already know.
