Hi Maria. I am sorry you are herxing. Although I agree that exercise is beneficial, there are times when it is better not to. I would wait until things let up. It is not good to push past what your body is able to do.
You can take a bath with four cups of Epsom Salts and either eight ounces of hydrogen peroxide or eight ounces of baking soda. Brush your skin in a circular motion from your feet up with a dry body brush. You can buy these brushes just about anywhere including Target. Soak in warm water for up to twenty minutes. If you have never done one before, I think it is better to try it for five minutes or so to see how you react. Some people herx from the bath and/or feel worse. Be sure to rinse off after the bath and make sure you drink a lot of water.
Do you take the supplement Milk Thistle? This is good for detoxing the liver as long as your liver is healthy. Taking regular Alka-Seltzer three to four times a day for one to two days during a herx also can help.
I hope you feel better soon.
