Cyn so sorry you are going thur this. I live with pain every day. I have fibro and RSV (perment nerve damage in my left arm from neck to fingertip) been going on for ten years, and if that boy has nerve damage God love him that he even moves at all. I will tell you about nerve damage just so you can understand what he might be going thur.
If you have ever had a tooth ache where when you open your mouth and the air hits it the pain sends you out of your mind. That is pain from nerve damage only up it by about 300%. This pain hits you so fast and changes so often that there is really no way to get a handle on it. Something as simple as someone walking 10 feet from you will set it off. The movement changes the air around you and that changed air sets you on a new pain level. If you would hurt and that would be it you could get a handle on it but with it changing so fast and so furious there is nothing but challenge to trying to handle it.
I pray that this baby is not feeling nerve damage. It sounds to me like maybe something was out of the socket. I have that in my right shoulder and knee, when they come out and go back in, it is weeks of a harsh ache. Weather effects all pain, bad weather brings it on and good weather is a change so it is a challenge again. If ya give him time and keep his nutrients up (yes folks lack of nutrients can increase pain problems by causing muscle spasms and they can cause bones to leave the socket) he can heal enough to pull through this.
Praying for you Lady chick
Praying for you and yours Cyn hang in there
