Pruney fingertips randomly. This be b12?

I have had this for a long time and it's bothering me now. My fingertips seem to get pruney on random intervals. Especially my right ring fingertips. Today i woke up with three fingertips just prickling and hurting even tho i wasn't sleeping on it. Can this be b12? I have been taking b12 supplements for 10 days now from prescription i share photos of my bluish nails as well and the pruney fingertips. I also noticed beau's lines on all of my fingernails almost 13 days ago. Which by the way after meds the dent on my thumbnail specifically seems to have gotten closer to the tip. I usually get Shortness of breath with stairs or running or leaning over to clean my feet in the shower but it seems to be episodic it sometimes is worse than the other times. I have a diagnosed electrical heart issue which i was given bisoprolol and Trimetazidine for. With the b12 supplements. The pruney fingertips have been a thing for a year now. It's so much worse after just normal dishwashing.
