what is a cluster headache...lately this headache is kinda just on the side of my head. I didn't have it for the first time Monday and was so happy but it came back yesterday. It is not enough pain to take an aspirin but I am still upset over it.
Lots of times stress and tension can cause these cluter headaches, esp. if you hold your stress or tension in your shoulders or neck. You said you are now on Zoloft, if this doesn't help, an anti-depressant that helps the headaches is Cymbalta. Hope this helps you!
