Hi, @Macca1961. I haven't had that experience, but wanted to welcome you to the site.
I'm sure you're team is thinking of what is best for you, on balance. If you're already getting extreme tingling, and pins and needles I can understand them being concerned as that tends to be cumulative, so would continue to worsen through treatment , and if it got bad enough, it may not reverse after treatment finishes.
Having said all that. Nothing is certain yet. Wait til you go back on Friday, and be led by your team.
Take care,
Lyn
