I posted about this in another subforum as well - I am only 20, but I keep developing problems with my joints and tendinitis, and am almost constantly depressive/anxious/lethargic without any real cause. I have chronic tendinitis in my elbows for 14 months that will not heal properly, even with rest, and a swollen right knuckle that is painful on extension and flexion of my finger. This swollen knuckle has been becoming worse the past 6 months - it started out as just tender, and is now larger and more visibly swollen, hurting especially when I wake up. Earlier last year I had a bulging disc that took about 8 months to properly heal, and recently I've developed pain again. I do calisthenics, but nothing dramatic or substantially difficult.
I have come to the conclusion that my elimination diet must be continued. I already fixed my severe GERD (waking up with vomit in my mouth), stomach pains, and post nasal drip by removing onions, garlic, and green onion. I know my keratosis pilaris goes away and comes back after a year long experiment with oats and wheat.
So what is left? Lots and lots of nightshades...I typically eat at least 500g potatoes per day along with tomatoes, tomato paste, and often even eggplant. I have this phenomenon nobody else can describe, only if I eat a meal of plain potatoes. Severe nausea, lightheadedness, cold sweat, develop - I thought this was coincidence at one point, or maybe I had potatoes high in solanine, but it happens to nobody else I eat the same potatoes with. I thought it really must have been a coincidence... I had started eating rice mixed with potatoes instead of a mono-meal of potatoes and no longer had stomach pains. Yesterday I ate a meal of about 600-800g boiled potatoes and had the same reaction, and am convinced nightshades might be my last problem food.
So, back to the elimination diet I go
I am too bothered by joint pains and further inflammation when I am only 20. I also bought a book from Professor Jonathan Brostoff, I hope to find some good information in there on food allergies/sensitivities.
