Sensitivity to Sound
Phonophobia is the word for sensitivity to sound. People with ocular migraines tend to be more sensitive to noise than others. This phonophobia often co-occurs with light sensitivity.
Noise can aggravate the headaches caused by ocular migraines. One way to deal with this is to avoid noisy environments or use a white noise of your own choosing. It is a bad idea to completely avoid sounds because you have phonophobia. Utter silence can actually make you more sensitive to sounds and result in more painful headaches.
Nausea or Vomiting
Nausea is a feeling of sickness or discomfort that often precedes vomiting. Not all feelings of nausea result in vomiting. Many times, this sick feeling is brought about by underlying health conditions that don’t have to do with the gastrointestinal tract. Migraines are one of such conditions.
If you have ocular migraines, you’ll likely experience nausea sometimes. It may or may not end up with you vomiting. There is evidence that vomiting may actually help relieve migraine headaches [7] but the reason is not crystal clear yet.
Conclusion
Ocular migraines scarcely need treatment. If the symptoms suddenly begin to worsen or happen more frequently, you should see a doctor. While rare, people who often suffer from ocular migraines are at greater risk of permanent blindness in one eye.
