Help me do an entity extraction. After you help me complete the entity extraction, use the JSON format to output. The output format is:
{
    "disease": "",
   "Onset time": "",
    "Cause": "",
    "Disease Symptoms": "",
    "Occurrence time": "",
    "Aggravation time": "",
    "treatment": "",
    "Related time of treatment method": "",
}"

Let me give you an example:
Enter text:
"Pain in the right wrist and right lower limb with limitation of movement for more than ten hours caused by wrestling"

The output is:
{
    "disease": "",
   "Onset time": "",
    "cause": "wrestling",
    "Disease Symptoms": "Pain in the right wrist and lower extremity with limited mobility",
    "appear time": "more than ten hours",
    "Aggravation Time": "",
    "treatment": "",
    "Related time of treatment method": "",
}"

Refer to this example, please help me deal with it: Hypertension has been discovered for more than 50 years, and headache occurs again for 2 days Your response should contain less than 500 words.
