Hi!
Post blow to head, you can have several symptoms such as disturbed sleep, headache, vision and hearing problems, nausea, vomiting etc. If headache and nausea are persisting after three weeks and a new symptom (blurred vision) has developed, then yes, you must immediately get this investigated. It could be part of concussion. However, it could also be a symptom of subdural hematoma or a brain bleed. Please consult a doctor immediately. Take care!
