I took this supplement as Arthrem for arthritic joints, Had had great feedback from friends and pharmacist and really thought for a while my joints felt better, then within a few weeks when on 2 tabs per day I developed fevers and rigor attacks regularly every 4 days. This was delibitating so I discontinued the drug and the fevers stopped. After a month I tried again and within 4 hours I had the worst attack ever Fever of 40 and rigor so bad I bit my tongue, Have not taken it since and no more attacks after 6 weeks. Interestingly I was suspected of having maleria way back in 1988 after being bitten by a mosquito ion holiday in Papua New Guinea could this be significant? Could I have developed an immune response?
