oh Violet, please do not think about bad things.ladies have short uretra and single 'cuff' (gents are lucky, they have two of them!) on it therefore we are often subject to some inconsistency, especially if we have more than one child. Then, night wetting might be a result of stress - I know that for sure becasuei had it several times when I was worrying too much because of my daughter etc. Finally children do that because they are stressed too - why we should be different? Cold bedroom also helps for involuntary wetting, as well as infection might be a case too.ALS takes out only motor muscles. Urination is controlled in its most important part by so called autonomous neural system, which is comptelety differernt from motor one. it is what directs our guts peristaltics, our bladdder, our heartbeat etc. And you know that people in ALS die not because of their heart is stopped, but because their diaphragm can not move anymore...So do not worry, seek GP appiontment if it hurts you and let me tell you that you'd be ok finally.
