Discomfort after brachial plexus anesthesia

First of all, bruising is a sign of subcutaneous bruising, which is related to brachial plexus block, and I assume you were given an axillary nerve block, where local anesthesia is injected into the axillary nerve sheath (somewhere in the axilla) to block the brachial plexus branch. During the puncture, blood vessels were accidentally injured, resulting in extravasation of blood into the axillary sheath. Because there was no effective compression to stop bleeding after the puncture, or the compression time was not long enough, and the compression position was not correct, blood spilled from the axillary sheath into the skin, which would cause large bruises under your armpit!

Secondly, I felt electric sensation in the palm of my hand when I reached out. This was because 1 nerve was slightly damaged when I punctured, and 2 blood exudate had a slight compression effect on the nerve after deposition. So will cause your inductance!
