Status update. I stopped the fish oil a while back and haven't had a panic attack since. However, I've had some other "interesting" experiences. Maybe I should start a separate thread for this, but these new reactions may be related in some way.
I had started the high dose fish oil after reading up on the Nemechek protocol in which high-dose fish oil is used to address inflammation. The protocol also treats suspected SIBO using Rifaximin. So I asked my functional medicine doc to prescribe a course of Rifaximin to see what effect it would have and as an empirical test for SIBO. At the same time, we decided to address my high blood pressure and I started on Losartan. While I don't like pharmaceuticals, I wanted to treat my high BP because it would be a shame if I had a stroke while trying to figure out the root cause(s) behind all this. I liked the idea of Losartan because it also has anti-inflammatory properties.
Last week I started experiencing joint and muscle pain, insomnia, and headaches. For a moment, I was wondering whether I had been bitten by a Lyme tick or something and then I realized that these are all possible side-effects of Losartan. I stopped both the Rifaximin and Losartan a few days ago and these symptoms have mostly resolved. I plan to restart only the Rifaximin in a few days in order to test whether my symptoms could have been a herx due to some SIBO die-off.
Anyway, if it was the Losartan, then I wonder whether my symptoms were due to increased nitric oxide. Both Losartan and fish oil increase NO. If it's due to increased NO I wonder if this sensitivity is some sort of healing crisis. Increasing NO is supposed to be a good thing. And most studies I've found indicate that NO should help to decrease inflammation, boost the immune system, and
decrease associated symptoms such as anxiety.
I suppose an easy experiment would be to take some L-arginine or Viagra to see what happens. Both of these increase NO levels.
There is also
this article from Selfhacked on L-arginine which mentions that:
Too Much L-Arginine May Encourage An Autoimmune Response
Nitric Oxide can react with Hydrogen Peroxide in the body to form free radicals [R].
These free radicals can cause oxidative damage and cell death.
Because of this, too much Nitric Oxide in the body can lead to an increased risk of an autoimmune response [R].
High levels of L-Arginine could encourage Nitric Oxide buildup, causing this response to occur.
