well, I made an appt to have it removed on Thursday afternoon (it's Tuesday) but my back was so bad today I decided enough was enough and pulled it out while I was in the bath a couple of hours ago. It was really not painful at all just a little fiddly getting a good grip on the strings, it wasn't even as uncomfortable as pulling out a tampon!
Anyway I took two paracetamol just in case and had a nap. 4 hours later my back pain has completely gone and I don't feel down in the dumps any more hurrah!!! I just hope my other symptoms disappear as quickly as they appeared. I will never have this again.
