ok I went to gym yesterday trained fullbody as usual to keep building good foundation back up. I do 2 on 1 off 2 on 2 off. Went to do normal day 3 routine today to mix it up usaually have sat off. Anyway did my Alt bi db and then my curls then went to squats pulled off 60x3 @ 10, 10, 8. So after I'm done I get this shooting pain in my head like a migraine. Have got this before but not nearly as bad. Have any of you ever got this? What should I do?
