I haven't been able to find the meds anywhere in China however my doctor in the UK has finally agreed to prescribing me the medicine. Now got to wait it out until it arrives.

It's got considerably worse. This weekend has been awful. I went out to the shops and had to come back because I was in so much pain. I tried looking at my computer later in the day and that was painful - which has never happened before. I spent the rest of the evening in bed and the following morning. Looking at the computer now is fine - thankfully.

I'm getting so frustrated with it all.
