I came to europe last month and all of a sudden i had stiffness and severe pain in neck, shoulder, both hand and finger joints, mild fever and flat reddish rashes in under arms and thighs. As per doctor advise, I took aspirine, caltrate vitamine D3 and voltarene L.P.75mg for few days. I had noticed blood in the stool and stopped the medicine. After 15 days the pain subsided in the neck and hands but slight pain persist in finger joints. kindly advise
