What are you scared it could be?
None of the details you've provided scream anything sinister. Maybe if you tell me what you think it could be, I can help reassure you it isn't.
We're all in this together, and we've all struggled with this HA. That's why we're here.
But everything you've described sounds like a bruise, or an ingrown hair, or perhaps an ingrown hair you've turned into a bruise by poking at it.
If I took my finger and poked at my arm all day, I'd probably have a bruise tomorrow.
How often have you been rubbing, poking, prodding, squeezing the affected area today?
