@justwow Hello, if it will be a help let me pass you my experience; I had radiotherapy all the way and rejected any intervention but as a result after 3 years i have developed Radiation Induced Bracial Plexus in other words I have lost the ability to use my arms.

During and after radiotherapy for some time I couldn't swallow, taste etc. but within the following 6 months I was over 80% recovered from everything until one day(3 years later) I started feeling tingling on my neck and within next 18 months I have lost the ability to use my arms. So there is no guarantee also for Radiotherapy, nevertheless I have been told that a cut can heal but for a burnt nerve there is no coming back; I really want to verify this with the doctor that has given you the heads up on this matter, if you could pass me his/her details I would like to get in touch with him/her because whenever I talk to a doctor about RIBP they seem to be surprised, I have never met a doctor that is aware of this side effect.

In short, if I would go back in time; initially I wouldn't like to go trough this but since it happened I would go for an intervention since the side effects are more or less proceeds the same way.
