No one here is medically trained that I am aware of, but fwiw:
Assuming you have Lyme and/or other tickborne infections, the symptoms you are having might be from the massage annoying the bacteria and stirring them up.
Whether that is caused by some sort of toxin, I wouldn't know, but your doc should be able to tell you. Hope you feel better soon -- and let us know what you find out, ok?
Another issue I am having is after a deep tissue massage or a trigger point massage (I have been getting these because of my leg issues) I feel sick the following two days. Could this be another sign that I have some sort of toxins building up in my system?
