무릎에 코르티손 주사를 진단 도구로 권유받았습니다. 의사는 주사가 효과가 있으면 염증이 있는 것이고, 그렇지 않으면 내부 손상이 있는 것이라고 말합니다. 의사가 맞나요?
Cortisone shot as a diagnostic tool in the knee what does this mean. If the shot worked does it mean inflammation? If not internal damage. Help
I have been advised for cortisone shot in my knee, as diagnostic tool. My doctor tells me if the shot works it means inflammation if not, it indicates internal damage. Is my doctor right?
