Mate my sympathies.
After the "snip" I split a couple of stitches jumping a child proof gate.
I can imagine the discomfort is similar.
I also know you have had a couple of growths removed and so have I so just knowing this is going to make you think the worst.
I had a melanoma removed recently myself and believe me in the same position that is what I would think.
Glad your nut will come out of this one OK. Just no before and after pics.
