The famous Look Thung (Thai folk song) singer said the pain was so severe he was unable to move his body.

“I was admitted to hospital on Wednesday morning. I felt the pain in my back. Previously, the pain went away when I did a workout. But, I was unable to carry on doing that because my body could not bear it anymore.

“With dwindling energy, I’m getting weak physically. So, I came to let the doctor check the cause of the pain. I had a T-scan yesterday and tomorrow we would know the result,” the 70-year-old Chinnakorn said on Thursday.

Asked whether the symptom was a side effect of the chemotherapy he received after being diagnosed with colon cancer two years ago, Chinnakorn said: “Possibly, it could be. My illness became resistant. To put it simply, I don’t know when my time will come.

“I feel like fish in a floating basket. I don’t know when they would come to take us for cooking. The doctor suspected that [the pain] stemmed from an infection. But, it’s already infected, so we need to know the cause. It’s good at hiding, though.

“I still feel the pain from time to time. When I came to see the doctor, I could not move my body at all.”
