Still in pain 2 months after coil fitting + work worries

[Brownbear17]

It's been 2 months since having the mirena coil fitted. I'm still experiencing pain/discomfort and have had 1 hospital admission since having it. I'm experiencing bad back pains/aches and feel shattered all the time. This is effecting every aspect of my life, I'm struggling at work and have been taken off nights til 'my health condition stabilises' I feel like I've been put on a time scale and after my next hospital appt in November I'll be expected to go back onto nights. It feels like I'm expected to be better just because I'm under the care of the hospital now. Stressed x
