Is there been any published research or do you know of any outcome studies with stem cell injections for nerve injuries from radiation. Specifically Radiation Induced Brachial Plexopathy
You can try to intake melatonin, at doses no lesser than 200 mg/day and also to apply a 30% melatonin gel in the area to be irradiated (before the radiotherapy). It works very well. I did it in myself and I didn't have any problem. Furthermore, there are two clinical trials in Spain using melatonin in cancer treated with chemo/radiotherapy. Results are very good.
