Maybe you’ve tweaked something in your neck that gets irritated with your arms above your head. Sometimes when my neck or traps get really worked they get so tight they like pull on my head so much I get a terrible headache.
Somebody else posted this a few weeks back, Yo Eliot shows some good stretches for neck/traps about 2 minutes in.
I would be careful here, Simo said it above, if you’re worried you might see a doctor.
Get your traps and lats released and keep training.
I get those headaches too on occasion. I usually try to keep going until I’m done and then put an icepack on the back of my neck.
I used to get pressure headaches every heavy session. They hurt bad and ruined the rest of my day. I tried to control the strain in my face/head and it helped but it was just one more thing to think about during lifting. I bought a lifting specific mouth guard and it has helped tremendously. Might be worth a try. I think mine is a 3ds guard or something?
This could be a neck issue. I have a collapsed disc in my neck C5 - C6 which is narrowed and has some calcification (it’s from an old motorbike accident). If I spend too much time at my desk looking at the lap top I get tight in the neck and this can cause headaches as well as numbness in my arms and hands.
When I get the pressure headaches they fall into 2 categories. 1. Those that aren’t too intense and I can follow marks advise above and often train through as long as I don’t hold my breath too much when I’m training.
2. Those that are bad and I can’t train through no matter what. In this case I take a few days off, get a massage or adjustment for my neck. If it doesn’t go away and reoccurrs at the next training session I would go see the DR.
It could easily be a neck issue, I spent many years with my neck cricked back belaying as a climbing instructor as a teenager and my necks never been the same since.
I’m going to have a look at some of the release methods and stretches that @FlatsFarmer and @MarkKO suggested, as the little bit of work I’ve done on them so far seems to be “hitting the right spot”, so I’ll try and hit them hard over the next 2 days, ready to train as planned tomorrow.
I’ll make sure I have painkillers on standby in case I have to go @T3hPwnisher style. And I should probably get round to signing on to doctors anyway, so I’ll get on that. Thanks for the input guys @mortdk and @wanna_be
To clarify, I am opposed to painkillers. I will take headache medicine, but opioids I avoid as much as possible, and even anti-inflams I am not a big fan of. I find I need an awareness of the pain so I can better track it.
But in either case, hope recovery goes well.
When I say have painkillers on standby, I literally mean buy some because it’s such a rare occurrence for me to use them. I could count on the fingers of one hand the amount I’ve taken in my entire adult life.
Having said that, I seem to have started falling apart in a pretty big way recently, so I guess new tactics may help.
I get these kind of headaches from time to time too, usually it’s a neck and trap working thing, pull-ups usually kicks them off too. I’ve found band pullaparts and drinking a ton of water helps, maybe it’s slight dehydration too.
I’ve spent the majority of the day, in between looking after the kids, trying to stretch out my neck and traps and it’s feeling much better already. I’m going to retry the session I bailed on tomorrow and operate as if it’s going to go to plan, but have a few painkillers with me in case.
I got told this stretching neck thing a while back that has worked wonders, you need to stand straight up, shoulders relaxed, back relaxed, look down, rock head slowly left to right about 10 times, then still relaxed, put left hand on head and it sort of slightly pulls and stretches for about 10 second s, same with right hand, then both hands, then both hand as fist under your chin and push up very slightly, it’s made my neck feel a ton better .
I liked it better when I was 20 something and I didn’t have to worry about this mobility crap.
But thank you, I’ll definitely throw that into the mix.
I am hearing you there mate
Yep getting old is fucked, but getting old and being like everyone else the same age is even worse!
Yep this is it. I don’t mind being older but I still want to be able to move weights and move my body like a young(er) man. I like to looks the kids give in the gym when they see an older dude out lifting them. 
Yes, it sucks. I could spend an hour in the gym doing prehab. That’s just not feasible so I’ll have to find a balance. I’m hoping to put together a warm up that covers all the bases once I’m back to normal.
I swear you guys are just making up mobility as a practical joke and I am NOT falling for it.
I think this too. I hear everyone talk about mobility or lack of it. Isn’t that just the bit in every lift where it hurts and you push through it !!
Work for today:
Seated press: worked up to 47.5kg x 10
Then 5 x 10 @ 25kg
Squat: worked up to 82.5kg x 10
Then 5 x 10 @ 50kg
Pull ups: lots
Abs: some
Notes:
felt a few slight twinges in the back of my neck and a vague headache, but nothing to write home about. Whatever I did worked so now I can stop doing it. Thanks to all those who offered advice @simo74 @T3hPwnisher @I_Luc @FlatsFarmer @MarkKO @mortdk
mostly happy to just get through the full session without any drama today. Felt like a perfectly fine session, nothing special.
I seem to have trouble pushing myself hard on squats, and I think that shows in my lack of progress in them. I can push myself hard on deadlifts, but not squats for some reason. Work to be done there.
Surely you mean keep doing it?
