Hi, I had a coil fitted (a contraception device) 4weeks ago, and I'm not sure if it's anything to do with why I'm feeling ill but I was wondering if you could help me.. For the past week I've been feeling drained, can't be bothered doing anything around the house I have no energy to even look after my 4 months old son, I feel sick, I've lost my appetite to a lot of food can only eat sweets or chocolate if I don't feel sick at that moment, I have lower back pain, my bowels are not normal, I have a fever and a bangin headache my temperature is 38.2, thank you hope you can help me.
