DLA medical I've just had ?

Sounds as though you over egged it to me. Why on earth would you not be able to make a drink? You are not totally paralysed so therefore not totally helpless - don't think you are helping yourself. Not doubting you are in pain etc and can see why you would not be able to get out of the bath (actually don't see why you would get in one if you can't get out) but don't believe you can't even dress yourself - whats wrong with your arms?
