injections

My dependence on crutches started within one hour of an ultra-sound guided injection at Charing Cross Hospital, in London.

Is it unusual for a patientl to pick up a supposed box of Hyaluronic Acid from an outpatient clinic, and then give it to a doctor in ultra-sound to inject it into one?

I'm cynical of doctors, especially ones in hospitals, and suspect that a corrosive substance was injected into my hip hastening the need for a total hip replacement (THR). Essentially I believe that I was used as a guinea - pig by these doctors at Charing Cross Hospital, in London.

Someone please try, and alleviate my fears please!

Big Steve.
