I was at breasts last night and suddenly after eating dinner felt this pain in my right ads and right temple. It started slow at first but increased in intensity. I finally excused myself and went to get something else to eat. I thought it was the food that did it.
I went to my car and drank some water and rested to see if I could shake it off.
The ab pain subsided after 20 minutes but the right temple had an ongoing, pain. I found myself taking deeper breathes which seemed to help.
Driving back home I stopped on the way to lay down in the backseat, when I woke up an hour later, I felt better.
I went home and went straight to sleep, and this morning I feel fine.
The last time this happened to me was in college we were drinking beers and I thought it was a hangover. Anyway I am 27, male, and otherwise extremely healthy.
At one point, when I started meditating a bit in the car I could sense there was minor pain and pressure throughout the whole right side of my body.
I hope this helps the others on this thread.
