i did a set of 20 rep squats that were not that heavy (155) and on the 18th rep, i got a splitting headache. that was on friday and i have pretty much had a headache since then. yesterday, i moved my head the wrong way and it came back, full force.
based on the way it feels and how it came back, i'm fairly certain that i've strained some part of my neck musculature (probably my upper trapezius, right?!). if anyone has any suggestions about some rehab/recovery steps i should take (other than resting and eating fistfulls of ibuprofen) they would be much appreciated.
