Sounds like adrenal fatigue.
We DO eliminate a lot of toxins through urine and it is toxic - hence the urgency to eliminate. I find that vitamin C is the antioxydant that is most helful in helping out. (It will also helps with your lymphnods at some point lymph nods imflamation were a symptom reminding me to take vit.C) I like cranberry too - because it is full of natural vit C AND will prevent urinary track infection..
I strongly suggest you have a look at the adrenal fatigue forum here at Curezone
as well as read my blog: http://curezone.org/blogs/fm.asp?i=976142
Remember ichy means zinc deficiency - supplement oral and apply a cream (any diaper rash cream will do ) topically.
Furthermore fatigue = adrenal fatigue OR allergies . Pay attention to the food you have eaten when you feel tired and stay away from that food for a while. ALlergies come and go- but eating the same food every day may lead to candida related allergy.
