About three weeks ago, I was working out at the gym. I was doing a chest press, and it started getting difficult, and I suddenly experienced a big pain on the left side of my head. I have no idea why it happened but it may have been due to improper breathing (but I'm not sure at all.) As I came back days after, the pain came back when the weights started getting heavier, so I took about 2 weeks off from working out.
The pain is now completely gone, and I go workout with the same weight, but with more precaution. However, a lot of the time, up to 2 days after working out even, I have slight tingles in my head. Sometimes in the back of my head, and sometimes to the side. Right now it's at the top right corner of my head (I think shere a vessel is) My friends say it could just be a slight tingle from muscles twitching or unimportant blood vessels.
I would appreciate your help a lot, because not sure at all whether these very slight pains are normal (up to 1 or 2 days after) or not.
