Gwenny
Just a little note for your sister. The pain pills and patch especially for those no pill guys make people very weird at times You wouldn't believe what my husband said to me and many nuses thru this process. Even being a nurse myself didn't help my tolerence. It really got to me.
Tell your sister to walk away is ok I walked out of the hospital one day when I had had enough. His Dr told him off for the way he talked to me and for some reason he got the message. Even though I knew the cause the words just stung too much. It's ok to do something to help yourself while you help him. I wish you all the best and Gwenny your sister is lucky to have you. I had noone and pat yourself on the back for being such a great sister.
