Thanks for the replies guys

I experienced the worst arm coldness/numbness I have had so far today, but I’m only 3 days in since it initially became apparent. I have noticed that repetitive movement (at least today) triggered the sensations. Mentally, I’m doing better and have been sleeping. I have come to the realisation that I’ve done all that I can do, and I should try to enjoy and get on with life as much as I can. I think if this persists for a week or two I will contact my doctor
