I do have spasm in upper abdomen which is exactly below the rib cage... It started 2 weeks before and slowly it radiates throughout the body. because of which i started to feel as if I have spasm in all parts of my body. Doctors can't diagnose what is it exactly and I have been painkillers. I get the pain back as and when the effect of painkiller goes off.. what could it be? whom should i consult?
