This is my first post here and I am asking for help because I have successfully treated a number of things that had been bothering my life already but there is still a big piece of the puzzle I haven't solved yet.

A few months ago I had the following problems (26yo male, 6'2 150pounds)
- Chronic constipation
- Cold hands, feets
- Arm injury that doesn't heal. I get great relief from trigger point massages but it's not really going away. This is my worst problem because I can't work as much as I want.
- ADD
- Anal itching

Since switching to the paleo diet, constipation, ADD, Anal itching, they all went away. I still have cold hands, and my arm injury. I do believe it could really be candida because whenever I take coconut oil, garlic or ACV in good quantities, I get big headaches. I also supplement a fair bit. BVitamins, A, D, etc.
I have recently stumbled upon a possible avenue of improvement. My sister has Fibrocystic Breast disease and I probably have some low-iodine symptoms too since I just found out that in our household we never used iodized salt at all. And we rarely ate sushi, and sea vegetables, like most people. I have started to supplement safe doses. I have 750 mcg kelp capsules and selenium, and I bought salt!! So cheap. The results for this are pending.

I want to know if I have to get serious about Candida detox to cure the remaining two problems I have :
-cold hands and the arm injury that doesn't seem to heal.

OR is it a thyroid problem? What can I do? I have had cold hands for a very long time. I joke about it saying that I'm a Vampire. It seems to be becoming the truth!! :D
