Why can't I get relief from detox symptoms?

I have tried salt loading, sauna, and Epsom Salt baths. They have provided no relief. My symptoms aren't unmanageable, but I find it very frustrating that I can't get past these symptoms and feel like I will never get the toxins out of my body.

I have only been on the Iodine protocol for 2.5 months. However, 1.5 years ago I started to supplement MSM and got hit hard with detox symptoms (mainly frontal lobe headache). I wondered why MSM was causing this so I researched MSM and found that it mobilizes toxins. It made sense that toxins were the cause of my frontal lobe headaches because I had been fighting what I believe to be a candida overgrowth beforehand.

So I tried to blast my detox away with MSM, and added chlorella and activated charcoal to try to help bind the toxins out of me. It hasn't seemed to make a difference. I have had this frontal lobe headache every single day for the past 1.5 years. Usually it isn't very bothersome, however some days are stronger than others. It has been at its worse right when I introduced MSM, then again when I introduced chlorella, and again when I started supplementing Iodine. I also tried stopping my MSM and chlorella supplementation for 2 months to try to see if I could get the headache to go away, but it hung around the entire time.

I would say the headache has been its strongest over the past 2.5 months while I have been supplementing Iodine hoping it would help further detox.

It seems to me that my symptoms have to be toxin related, but it just doesn't seem possible that this detox can last for 1.5+ years. I also don't understand why I can't get any relief from things like salt loading and sauna.

Does anyone have any ideas that can help me? Is it possible my liver and/or kidney aren't working properly? I feel like these same toxins must be circulating throughout my body but never getting released. Any tests I should look into having done?

Thanks
