Oh, Larry, ouch! So sorry. I'm glad you feel OK, but please seek medical care if you start feeling not-OK. Does your medical insurance give you access to NurseLine? It's a 24/7 hotline of nurses who will do a phone evaluation to help you determine what level of care you may need. My experience with them in December when I had a head injury was excellent. I didn't want to go to the ER and her assessment confirmed that it wasn't really needed. Sometimes you just don't know. It was very helpful to talk to an RN.
Can someone check on you this evening to make sure you're feeling OK? You may want to send a message to your doctor, letting him/her know what's happened. Please take care.
Vibes you continue to feel well!
