Hemicrania Continua

Hemicrania continua be existent in both continuous as well as remitting forms. In the beginning, headaches occur every day for years. In the latter, periods of daily headache alternate with pain-free remissions.
Rebound Headache

Chronic daily headache patients who consume analgesics more than two times a week to relieve headache pain tend to develop analgesic rebound headaches. This may lead to development of transformed migraine.

Therefore, headaches become more often as the increasing of medication use. Analgesics that used to be able to completely remove the head pain simply overwhelm the pain and then become ineffective over period of time.

In certain cases, chronic daily headache patients are awakened from their sleep when serum analgesic levels drop below the pain threshold. Then, it triggers a more severe and intense headache. These patients will consume a stronger analgesic to remove the pain upon awakening.

If they have to stop this chronic overuse of analgesics, these patients will experience:

  • Intense withdrawal symptoms
  • Vomiting
  • Nausea
  • Sleep disturbance
  • Irritability
  • Increase in headache
  • Depression

The withdrawal phase lasts between 2 to 4 weeks, but it is followed by a significant decrease in headache duration, frequency and intensity. In specific cases, postwithdrawal headaches would become erratic and then finally remit.

You should consult with your doctor and other health care professionals to get a better knowledge and information about Hemicrania Continua and Rebound Headache.
