I felt the same way! I had the horrible swelling in my knees and feet. Just give it time. My swelling is completely gone now 3 months post removal. I have been through all the test and I will tell you the results are all inconclusive! I have had MRI's, tons of blood work,numerous X-ray's,and doctor's trying to remove fluid from my knees with needles!
I didn't really have any chest pains but sometimes I would feel a tightness across my chest.
The doctors are not going to admit all this is from Mirena.I felt like I was 26 trapped in a 80 year olds body.
I hope you start to fell better soon! Hang in there!
