Nope. Actually just had a copy of episodes driving home yesterday evening. Began 40 mg Nexium and powdered coral calcium supplement regimine March 22nd
The reason I called them cluster is because the pain was localized just above and behind my right eye. The stabbing or gripping sensation lasted for only 5 to 6 seconds: but occured about 3 times in 20 minutes; then one more time about 45 minutes later. I should mention I am due for an eye exam and probably an updated prescription for eye glasses, and occassionally have a wee bit of seasonal allergy related vertigo.
