Yes I know, indomethacin can be though and it is actually poison. Once I cut open a capsule to see what was inside and it was a kind of white powder but when I put a bit on my tongue, my tongue was burned and saw red ! So not very healthy stuff ...
I did the first indocin test 150 mg just before Christmas and I remember on Christmas eve, I was ill the entire day, pain everywhere, dizzy and vomiting the entire day. It was horrible but I did not want to give up as it is the only way to know what I have.
So one week later, I tried it again and ... surprise.. no side effect what so ever. Only quite some pain in my stomach that last for 2 days but that went away. Now I can easily take 225 mg without any side effect ! So maybe you can insist to try it again. As happened with me, can be you react totally different on it when taking it a second time.
The biggest problem is hemicrania continua, because it can look like everything else. There is an extensive study on the internet about it and they say the exacerbations can look like CH, PH, migraine, tension headache and SUNCT. So for people who have a continuous background pain with attacks that change character all the time, it is good to try the indomethacin to see what it does.
I have also lots of background pain 24/7 with the short attacks superposed, so hemicrania continua was what we had in mind first but the indocin worked only on the short attacks but did nothing on the background pain. So that is why HC was ruled out and a PH diagnoses was made. The background pain is now believed to be part of the migraine spectrum or some kind of tension type related headache. Yes, an indocin cure can reveal/rule out quite some things.
I have been very good for the last 2 month with very few headaches. I am sure it is because of the COVID lockdown that I am able to work permanently at home and life is more quiet and regular in general. Apart from getting some food and basic necessities, I haven't left my home since 10 March. 18 May some limited mobility will be allowed again.
