Thank you for your comments!
@arpie - I know - I feel like the evidence is there that the cold caps work. They're not exactly new technology. I would 100% try if I could. This attitude from the nurse is pretty on par with my ongoing experience at this hospital, so I am not surprised.
@unicorn3 - thank you for this insight. I have looked into the frozen caps but I don't know how one would keep it at the right temperature - surely it begins to warm up once on the head and thus isn't really stable. Plus this hospital say that no-one is allowed to sit with you during the infusion so I don't know if it is really an option for me.
@Blossom1961 - this is amazing! Thanks for this tip I am going to ask! I would do this in a heartbeat.
