Brief Answer:
Unlikely

Detailed Answer:
Good afternoon. I am Dr. Saghafi, neurologist practicing in the XXXXXXX OH region of the country. Tingling sensations are not indicative or suggestive of subdural hematomas. If after 3 weeks an SDH were developing you'd literally be having symptoms of significant import by now that would've likely landed in a hospital and quite possibly gotten you surgerized. Having said that I cannot GUARANTEE that NO bleeding occurred as a result of the impact. However, since you did not go the ER for any imaging studies it's hard to say.

The tingling may be the after effect of the strike to the head by the sign but that's superficial only. It would not be reflective of something going on below the surface of the skull.

I would recommend using warm compresses on that area a couple times a day for 20-30 min. at a time. You could use some Tylenol for pain if that's an issue but if there's really no pain then, I would've even go that far.

Make an appointment to see your primary doctor for a checkup if you're particularly worried but at 3 weeks out the chances of you having significant pathology in the absence of any other symptoms is so remote that I'd think members of the Polar Bear club getting attacked by a school of piranhas in Lake Michigan in the month of February would be more likely.
