ECH

I am beginning to get slightly worried and wondered if someone could help please.  I was diagnosed in December 2015 as being ECH and since then have been keeping a diary of my CH.  It turns out that I am getting a CH at least once every two weeks sometimes two or three times a day during that two week period.  I am finding this rather odd as I was given to understand that ECH meant that you had a CH for a few weeks and then a long period of remission before the next bout started.  This is just not happening.  I am also getting shadows, sometimes very painful shados in between.  I take Sumitriptan injections as and when I need them and also I take 25 mg of Topiramate in the morning and 50 mg at bedtime.  I also take manesium supplements every day.  I will shortly be seeing my Neurologist and will show him the diary but wondered if someone could please give me some advice as I am beginning to panic.  The CH are getting worse and I don't know what to do.  Thank you for reading this.
