I was chronic, started busting in 2012 and managed to end my chronic state and attacks completely at first. CH returned in few very weak cycles. I have not had a real cycle since 2015 and manage to keep myself pain free with Anti-inflammatory regimen and preventative or abortative busting. But IF things get out of hand, this is exactly what I get - continuous pain. I thought at first that after 30 years I have managed to develop a migraine in addition to CH and neurologist also thought so. Now I know we were both wrong, it was CH moving on to another side of my head. I think it (or he/she) is migraine-like continuous pain and not in regular attack duration because I have too effective treatments and it's trying to break throught (usual spring and fall).
I wholeheartedly recommend investigating busting further, also Anti-inflammatory regimen if you're not familiar with it already and also Herbal protocol
