Hello T Nation
I've had this problem continually for probably a year or so and it comes and goes. But every now and again, like right now for instance, a day, maybe two after benching my armpit will get super tender to the touch. I do plenty of stretching and warming up on bench beforehand too. I'm doing the strong lifts 5x5 and I've seen increases in everyone of my lifts except bench press.
3-4 years ago I could rep 225 3x10 quite easily. Maxed at about 315. At 6"0 185, I didn't think that was too bad. Now, I struggle with benching 185 5x5 and I have this cursed swollen armpit issue. I should note that it doesn't happen every single time I bench, but way too often if ever.
