I mentioned on the health boards about this. I have suffered from an excruciatingly painful shoulder for months now. Scan revealed a tear. I have tried all sorts of bras and agree about the horrible underwired sort. I have recently found some comfortable, basic ones from evans. (Some people would say I should lose a couple of stones!). The great thing I have discovered, as someone who cannot reach behind to do them up without crying, is that they can be done up first and then pulled on.
Why did I not think of this before. Shoulder a bit better, but the reason why I am awake now at this ungodly hour, is because,of pain!
