Hi, I haven t been feeling well for awhile, approx. 2 months. I experience headache, dizziness, muscle weakness, upper back and neck weakness. They have checked for Limes, rheumatoid arthritis as well as other blood test. On all of the four separate test that I ve been done from four different doctors, my sedimentation level was high. Back in March I went to a dude ranch, and was feeding and putting the farm animals. Could I have gotten a parasite from them? And if so could that cause my sedimentation level to be high? Or could this be cancer?
