Hi Dana -
I just replied to your previous post and hadn't read this one yet.
What kind of chemo is your husband being treated with? And are they giving him anything for the nausea? Also, why are they giving him chemo and radiation at the same time? That's not usually done (although I have heard of it).
It sounds as though your husband is being treated in-hospital? See my other post...you still need to have some of those questions answered, but get back to me with the type of chemo he's on and maybe I can find some info for you (or know someone who's had that type of chemo). The nausea could be from either the chemo OR the radiation...if his stomach and intestines are getting some of the radiation, that would probably cause some nausea. If not, then it's from the chemo, and can probably be reduced or perhaps even prevented.
How old is your son? If you think it would be better for him to see his father, even in a weakened condition, then insist on it. They can suit up your son in mask/gloves, etc. just as they do you. It's a judgement call as to whether he's better off seing his Dad this sick or not, but kids worry and sometimes our efforts to "protect" them don't work. I'm not suggesting that you SHOULD insist on your son seing his father, just that YOU should be the one to make that call!
I'll watch for your reply re type of chemo, etc.
