My father has been in hospital 4 times for gallbladder stones. Became septic 4 times. Doctors will not remove gallbladder as he is high risk due to health complications from years ago and now has veriousy veins. He is 80 years old. They put a stent in his bilary duct 8 months ago the and stones pass thru and he has had no problems, however, he had gb attack few days ago and was in hospital to rest gb. Now that he is home, he is complaining of muscle soreness all over his body almost flu-like. Took his temp and it is 97.9 so I know he doesn't have infection. Has anyone else had this soreness and what could have caused it? Any response will be greatly appreciated as I am worried sick about this.
