I had an ablation for heavy bleeding, it was done with a local anaesthetic. I wasn't warned how painful it would be. It was agonising. It didn't help and I went on to have a hysterectomy.
The coil has helped
Don't be fobbed off by medics trying to save money by telling you; 'its your age'. Keep asking for the help or test you want. I couldn't leave the house for more than an hour or so because I bled so heavily some months, and was left without the coil I was finally offered because the Dr who fitted them and then the nurse who did the pre-fit checks were away on holiday consecutively over a further 2 months of hell. Make the fuss, do not suffer unnecessarily.
