I was especially asking for personal experience because, as you found, swelling nor edema is documented as a
side effect of the
morphine. However, since I have been an RN
for over 10 years and was a pharmacy tech level A for several years before that, I am aware that there are more rarely reported side effects of medications that aren't documented!
So, again, was only asking about personal experiences with the use of Morphine ER.
