Crp symptoms and conditions

MY FATHER WAS DIAGNOSED WITH TEMPORAL ARTHRITIS. HE HAS BEEN ON PREDNISONE FOR ABOUT 5 MONTHS NOW, STARTING FROM 80MG/DAY. HE HAS TAPERED DOWN TO 40 MG/DAY,,BUT TH SIDE EFFECTS ARE STARTING TO BECOME UNBEARABLE.
WATER RETENTION,,SWELLING, MUSCLE PAIN,,WEAKNESS.
HE IS 80 YEARS OLD,,AND IT IS REALLY TAKING A TOLL ON HIM. IF ANYONE CAN GIVE ME ANY HELP OR INFO TO COUNTER SOME OF THE SIDE EFFECTS(MUSCLE PAIN AND WEAKNESS MOST IMPORTANT) IT WOULD BE GREATLY APPRECIATED.
THANK YOU.

My experience with Remicade has not been good. On one hand it did help with the crohns. On the other I developed weakness and tingling in my arms and legs, joint pain, ankle swelling, I have difficulty walking now. I also have numbness on the side of my face and occasional sharp chest pain. I find I am very depressed. I'm at my wits end. It is horrible bing in constant pain. I'm thinking of just going it alone without any medical help. I was better off as a 117 pound, 5-'9" lady with only crohns to worry about. Sure swallowing anything felt like glass but it beats this.
