I have not had any response to my question so I am following up on my own question of a few things that I have found to help a bit. Maybe some day this will help someone else if they have the same questions.

I am entering into my 2nd week of radiation treatments. I have found that warm Epsom salt baths help to sooth me and my down unders! I like the Lavender salt. I could not take baths after my surgery for 8 weeks per my Dr. But now that I can take them, I have found it to help sooth me.
Another thing that I have found helpful is Ice Packs between the legs. I wear a thin layer of clothing or use a cloth to keep the pack away from direct contact with my skin.
One more thing that has been great and this may sound a little funny... my husband went to the hardware store and found a Bidet Attachment that could easily be installed onto my toilet. By the end of last week I was so swollen that nothing seemed to help. I sat on the toilet backwards (facing the tank), turned it on very low just enough the hit where I needed it to hit and once the shock of the cold water hitting me went away it felt wonderful! I dont know how long I sat there just letting it run. I think it helped with the swelling for sure.

As I go into week 2 I am not sure what to expect but I will continue using these few tools that I have to help relieve some of my discomfort.

If I find anything additional I will sure post again.

Hope this helps someone, somewhere, sometime!

HUGS to all!
