Thanks for the replies - And appologies in advance for any terminology I use that you may be unfamiliar with, as I'm in the UK! It took her the best part of Sunday to get back to feeling anything like normal, although her balance has definitely taken a bit of a step backwards.

One thing this has done is encourage her to call the rehab department at the hospital. A couple of weeks ago, they sent her a letter saying that the doctors who saw her when she had to be taken into the A&E department had been in touch and requested that they contact her. The letter just said that if she was having any problems, she should call them for a chat and they'd then decide if help was needed. When she first got the letter, she said that she wasn't going to give them a call, because she felt like she was getting on OK and didn't want to "make a fuss". However, after this weekend, she decided (with a little bit of encouragement from me) to call them yesterday, and they said that they're going to send her an appointment for an initial assessment. Based on what she told them over the phone, they also said they'd probably be arranging for some physio sessions to help with her balance and memory to start with, and then see how she goes after that. So she is going to be getting some assessment and, hopefully, help.

And she's definitely going to be using earplugs from now on anytime she's in a noisy environment. I know that my dad probably isn't going to like it, but I also know from experience that earplugs are often vital for various reasons - I used to work as a DJ in a biker's pub, and went to a lot of quite loud concerts, which has left me with a bit of mild hearing damage, so I always use earplugs whenever I go to a concert now.
