I looked up the drug on the internet and apparently it's chemotherapy! I can't believe they asked me to inject myself with chemotherapy!. I've had 5 injections of that stuff and if I'd known that before hand, I wouldn't have had it.
Both the VS and the hyperacusis are hypersensitivity conditions caused by a malfunctioning immune system so it stands to reason that chemotherapy would cause a resurgance of symptoms. I feel really angry about this as it took me 11 years to get rid of it and I'm scared in case it takes me another 11 years.
Maybe because it was only 5 needles I will be okay, but they should have told me it's used as chemo! It didn't say that on the data sheet.
