Prayer Request

Please see a prayer for my dad as he is being admitted to the hospital tonight. Yesterday he was out trying to split some wood and bent down to pick up the chainsaw and threw his back out. So Mom had been feeding him some back pain relievers and he would not go to the ER. Today I think he finally agreed to go but my mom and Chris could not get him to the car due to the overwhelming pain so they called 911 to come get him and take him to the ER. So after a normal Xray, they think he may have blown a disc and will get an MRI in the morning. They are thinking that maybe some fragments of the disc are hitting on his nerve causing this pain. They said he said it is the worst pain he has ever had and he has had chronic back pain on and off for years.
So please say a prayer for him that the pain would ease, give the doctors wisdom, give him a good/polite medical crew (as Chris said they have not been very good thus far,) be with my family back home, and give them wisdom in making medical decisions.
Thanks so much!!!
