All, I am experiencing what my husband believes in cluster headaches in a new way. I've had traditional episodic clusters for 15 years. I've been using oxygen to abate them for about 2 years with great success. I have some history with anxiety and panic attacks but only in very specific situations such as flying. This is the time of year I would get my clusters but instead I'm getting cyclic panic attacks without pain. The opening sequence matches my clusters exactly with stomach pain and, bowel movement, and nausea and then becomes a full blown panic attack. I do not get the searing pain I've always had. Oxygen relaxes me but does not allow it to go away.
Any thoughts on whether this is a new way my clusters are presenting or just simply an evolution of general anxiety disorder? Thanks!
