Hello, I ve recently been recovering from back surgery and it seems to be slowly improving until a few days a go when my hip started to bother me, today, as I have been told repeatedly that I should walk so I took a walk down the driveway to the mailbox and back and later took out the garbage(all with the aid of a cane) later, after lunch, I was tired and took some ice and laydown for an hour and now when I got up, the pain in the hip is much worse. Is this a severe injury or am I falling apart a little at a time. I am 86 years old?
