By the way, since your personal experience could help me, could you give me informations about it ?
Sure thing! I'll keep it brief as I'm intending to write a more detailed report once I know more about the results of measures I'm taking at the moment.
Triggers in descending order of resulting symptom severity:
* Hard exercise
* Orgasm
* Stress
* Very hot or cold weather
* Certain foods (e.g. wheat, excessive sugar, alcohol)
Symptoms in descending order of impact on my life:
* Mood swings: Irritability, depression, anger
* Fatigue (physical and mental) and lethargy
* Concentration problems
* Memory problems
* Hands and feet especially, and whole body as well, get disproportionately cold in cold weather. Subjectively feels like poor circulation
* Poor coordination
* EDIT: Gut problems: Gas, constantly feeling like I need to go #2, slimy stool
* OCD
* Pain in lower back and feet
* Itchy skin lesions, dry and cracked skin
* Pain in legs and stiff and tender muscles and tendons in general
Seemingly helpful measures I'm taking:
* Chlorella. Rationale: I suspect mercury poisoning but don't know for sure. Chlorella can (ostensibly) help get rid of heavy metals, but is also just healthy in general, so no risk, and cost and effort are low.
* Bovine collagen. Rationale: Lots of skin issues that correlate with other symptoms. Lots of gut problems. Hoping that collagen can help heal the skin and gut, potentially calming the immune system.
* EDIT: Diet low on histamine and foods that trigger histamine release. Rationale: This is reportedly good for MCAS (Mast Cell Activation Syndrome) patients, and my symptom set is very similar to MCAS. This diet helps my gut immensely, more so than low-FODMAP which I also tried.
* Stress reduction. Rationale: It's a trigger for me, and it's implicated in many types of chronic health issues. I quit a stressful job and started a company. Practicing not getting wound up.
* Vitamin D. Rationale: I was deficient, and many people on the forums report improvements with sufficient vitamin D levels.
* Berberine. Rationale: Seems to help my gut significantly. Less gas, firmer and healthier-looking excrement.
*
Light exercise. Rationale: Subjectively seems to help blood circulation and helps a lot with muscle and joint aches as well as brightening my mood.
EDIT: With all the above measures I've been able to reduce overall symptom severity by roughly half.
