I had that when I was a kid for years and years, until finally, at age 12, my mom decided I go to a doctor to get that lump examined.
I didn't know it's that uncommon in women. I might have a genetic predisposition since my dad had the same thing and I was so little when I got it. But no one paid any attention to it. It would pop in and out all the time.
I recovered after being prohibited to even lift my schoolbag for 3 months and now I am trying to lift weights to get stronger.
But I lifted 20 kilos the other day and my hernia scar felt funny. Maybe I shouldn't suck it up and ignore the weird sensation.

I am glad you are better and I hope Henry never returns again.
