RE: Severe Pain HELP
been through this myself though i did it twice whilst doing military press on the smith machine.
i pushed a little hard, was burning up in the face about to explode then had to put the weight down on the last rep.
dizzyness, biggest headache of my life and sickness followed. the headache lasted for 2 weeks and it was pure banging.
i saw a phsyio and she did a couple of scans on it (what they give preggers women lol) and that seemed to ease it off along with a bit of massage.
IMO looking back i probably caused it myself from lifting my head forward during the lift. without a doubt it should be flat back on the bench.
