I'm having pain in my glutes, around the tailbone area. I have used the search function but found nothing about why this happens, could you please help me.

I'm doing the LP, my squat is 100kg and Deadlift 115kg. The pain appears to intensifie right after training the squat, even on non-deadlift days. My form is decent. I can't see any flexion on my videos or basic mistakes, maybe I have a slight overextension at the top on some sets, but I could be wrong. Here [are] video[s] of me squatting and deadlifting.

What's strange about it is that when I contract the muscles the way you do to hold your piss, I feel a sharp pain right between my buttocks and down to the tailbone.

Any idea what can cause this? It's starting to heavily affect my day because I can't sit for too long before it hurts so bad I have to stand, it feels like a burning sensation. I didn't have this the first time I did the LP, so I don't know what's going on.

I'm having the same pain right now myself. It's an SI joint issue that I have managed in the past with heavy squats. This knee injury has really fucked me up, and I can't squat heavy to fix it. I think the gait asymmetry caused by the injury has destabilized my pelvic situation, in conjunction with several old injuries. Mine hurts when standing and goes away when sitting, but the pain sounds similar. I've had three therapists look at it, and nothing has helped so far. Had to stop taking NSAIDs for my stomach, so there is no effective way to control the pain.

If you figure it out, let me know.

I had an undiagnosed SI injury with similar pain expression, and it's caused a few muscle spasms in the past in my lower back. It occasionally causes my back to go out. I've found the same as Rip... squatting consistently helps, and I also use a stretch between warm-ups and work sets when I feel the pinch/pressure. I don't go nuts with it – I just hold it for around 20-25 seconds on each side. If my sacrum-lumbar is out, it will self-adjust gently. I can usually continue pain-free afterward.

Rip, have you seen if you can tolerate Toradol? I recently started using it for acute issues because I figured if I continued to pound 800 mg of ibuprofen I was going to wind up in a similar spot. I found out about it when the hospital used it on me for a kidney stone.

I have some IM Toradol for emergencies, but the shit is very hard on the kidneys and I try not to use it casually.

My back acne has gotten so bad over the last few months that my wife demanded I go to a dermatologist. I was prescribed a regimen of doxycycline and a topical foam to help get rid of it. I know certain antibiotics are linked to tendon ruptures and before I start taking this stuff, I just wanted to make sure no one has heard of any adverse tendon effects or anything else that might interfere with weight training?

When I brought it up to the doc she seemed unaware of this, but I am almost certain it’s something I’ve heard before.

Cipro is the antibiotic associated with collagen problems. I know of no similar problems with Doxy.

Ah ok! I just wanted to make sure. I appreciate the response.

Don't use the same bath towel twice. I have also personally found I am prone to breakouts when taking pain meds. If you are on those, try to avoid them for a while.

Also Levaquin. The class in question is fluoroquinolones. You can ask your doctor or pharmacist if an antibiotic is in this class, or ask Dr Google. These antibiotics have become much less popular in recent years for a number of reasons, including the tendon ruptures. There are a few situations where they are probably still the best choice, but mostly there are good substitutes.

Doxycycline has other potential side effects, but is not a quinolone, so your tendons should be safe.
