In an attempt to diagnose illness I have had 7 CT scans in 2 years . Because of new upper abdominal right side pain dr ordered hyda scan. Should i be concerned about  the radiation?
I have headache for last 2 weeks. I had CT scan done 7 times and one HIDA scan in last 2 years but I have been fine for last 6 months. I am healthy otherwise and I never had headache in the past. I think my headache is due to the radiation exposure. What should I do? Do you think there is a permanent damage due to the radiation?
