Hi Icypole :)
I suffered during radiation too. was told soov cream was good for pain and itchyness. keep your skin moist. i was also on regular pain drugs for the pain. some of the other girls use cold facewashers and aloevera straight from the plant to help with radiotherapy. The number one rule is always ask your nurses before trying anything.
I also learnt this at school. might help your swelling.
During and after radiation therapy, you should do simple stretching exercises each day to keep full movement in your chest, arm, and shoulder muscles. The tissue damage from radiation treatment continues over decades, so plan to make these simple stretching exercises a long-term part of your daily routine.
This may also help the pain improve. only do a little bit - do not overdo it.
Hope this helps. You know where to find me :-)
