Good morning - as I have come to learn - inflammatory reactions are not swelling reactions. Two separate things. Quickly grabbed this explanation:
"Swelling is any abnormal enlargement of a body part. It is typically the result of inflammation or a buildup of fluid. Edema describes swelling in the tissue outside of the joint. Effusion describes swelling that is inside a joint, such as a swollen ankle or knee."
More: (I think of it as my nerves being triggered) and if left unchecked it will turned to swelling (edema pressure). But I agree, they are hard to untangle and happen together and we don't think about the separation.
Switching was mentioned but I have to check. Forteo also had issues - don't want to jump the frying pan into the fire! just yet! (they won't let me post the link but you can google the differences between swelling and inflammation.
