I had radiotherapy as, along with the Myeloma I also had Non Hodgkin’s Lymphoma which manifested as a tumour behind my right eye. You can’t feel the radiotherapy as it’s being done but you will hear a lot of noise from the machine. I had bursts in three different places so it moved around me and makes a noise when it moves. It’s not like an MRI where you move through the machine. You lay on a similar thing but the machine does all the moving. You will see lights.
Side effects wise it did seem to affect my appetite and I did lose some weight, which I put back on over subsequent months. The only other side effects I had were headaches, which stopped when the radiotherapy stopped, but that may be particular to me as mine was to the head.
I did feel a bit tired afterwards but this was minimal and I certainly didn’t feel any pain other than the headaches I have described above.
Your last question is it depends on you and your individual circumstances. I had it every day for two and a half weeks. Two weeks later I had a consultant appointment and learned it had shrunk it.
Hope this was helpful to you.
