Let me tell you a story.... True one at that...
On another forum, I read of a guy who has had lymphoma fears for at least 7 years. Upon reviewing the post history, there were no less than 4 CT scans, a couple of MRI's, x-rays and a plethora of blood tests. This person, poked and prodded to the point that nodes in his groin were permanently swollen. Of course, the swollen nodes had to be cancer. It had nothing to do with the constant poking and prodding over the years.
Finally, after doctor hopping for a bit, he convinced a doctor to perform a biopsy of the swollen nodes in his groin. We're talking about an invasive procedure done under general anesthesia! He posted constantly on the forum, worried that the incision was infected, and every little ache and pain associated with the surgery was sinister. Well, guess what? The nodes were fine. NOTHING! No cancer.
But that didn't end the worry and anxiety. He was back on the forum worried that they missed something and imaginary nodes began popping up in his neck again. Once you start that cycle of reassurance testing, it just keeps going. It has to stop somewhere, sometime.
The CT will show if there's anything going on. The key is to BELIEVE IT! When you get the all clear, speak to your doctor about treating the real illness. Ask for a referral and begin the healing process.
