I'm 27, male, 165 lbs, 5'11". I've been paleo for about 1.5 years, and I generally don't have much trouble being relatively strict about it (i.e. 30-75 g carbs daily, no junk food, zero gluten, minimal nightshades, no dairy). I eat quite a bit of meat (mostly grass-fed), eggs, coconut oil, ghee, and some sweet potatoes post-workout. I'm pretty fit in general. I supplement with 5k-10k IU vitamin D3 and 50 mg zinc daily. I've tried fish oil, but it seems to increase my acne.
Well, here's my troublesome situation: I have noticed in the past few months or so that I often get what looks like raised welts on my arms or legs from contact with seemingly innocuous everyday things (e.g. after carrying a box, I would get them on my arm); raised chicken-skin white bumps on my arms (keratosis pilaris, I presume?) that have recently become more prominent; itchy raised rash bumps on my arms and sometimes legs that last for a few hours; acne on my back and oily facial skin; and some pervasive hair loss with peculiar hair shaft symptoms consistent with alopecia areata, which is an inflammatory autoimmune disorder.
I had my C-reactive protein checked not long ago: My level was <0.10, which is significantly below the baseline of <0.80 mg/dL.
Could my problems simply be beyond the help of a healthy diet and lifestyle? I feel like I've gone through the paleo checklist of possible causes. Any ideas would be greatly appreciated. Thanks!
