Hormonal coil (IUS) and lower back pain

I'm on my second Jaydess (been using it for almost 6 years now), before I was on the pill (estrogen+progesterone combination) for about 6 years. Insertion is no fun for me, other than that I can only recommend it. Compared to the pill I have much lighter periods, period pain has significantly decreased (I get a little abdominal discomfort+back pain a day before the start of my period, and that's it). Acne stayed about the same as on the pill. I get a little breast swelling/tenderness for about one week every cycle which I think has slightly increased compared to the pill but isn't so bad. Sex drive and mood stayed about the same, if anything, my mood has become more stable on Jaydess actually (but that could also be attributed to me growing up I guess). Overall I'm satisfied with it

I'm hypermobile, and over time it has made my symptoms a lot worse despite my levels of exercise to strengthen. I'm now in pain regularly and sometimes struggle to sleep because of it. I've also started having migraines with aura and frequent headaches. Getting it taken out next week. It did however reduce my heavy bleeding to infrequent spotting, but I bled for 9 months straight after having it inserted.

Had kyleena fitted on recommendation from my doctor due to severe painful heavy periods, I have adenomyosis and suspected endo. Insertion was uncomfortable but not excruciating, the cramp lasted a couple of seconds and I was fine. Bleeding started within hours and didn't stop for the duration of use, I was having excruciating pain every day to the point I couldn't walk, feel my legs and awful tail bone pain. I booked an appointment a month later and my doctor said I didn't look well and removed it without me even having to ask. I wish it had worked for me but it just didn't. The removal was fine and gave instant relief.
