Unfortunately I have had to have many surgeries (stents, quadruple bypass, gall bladder, broken hip and very recently on my eyes and the list goes on!) so I have used the injectable many times and there has never been a problem.
The injectable can be reversed or altered much faster where coumadin cannot so it's much safer to be using the injectable while you know you have a higher risk (like during surgery when they will be causing bleeding by cutting into you 😀)
*Also just a quick note regarding injecting yourself...it's a small needle and doesn't hurt but the trick is to shoot it like a dart, a smooth quick motion rather than a soft pushing (if that makes sense!) When you push it in quickly you barely feel it at all! The first couple of times I did it, I have to do it on a count of 3 (in my head I had to count 1-2-3 and GO!) to work up my nerve but you'll get it, I promise!
So go ahead and have your procedure done, you will likely be at a lower risk of other problems once they are able to get a proper diagnosis when it's complete.
Best of luck to you, please keep us posted as soon as your feeling up to it!

I take Xarelto to ward off clots. I took warfarin prior to that. Before a recent colonoscopy I stopped Xarelto and used Heparin, similar to Lovenox, injections for 5 days, 3x a day. After the "colon scope" I started back on Xarelto and did shots 2x a day for 3 days. It's important to have the injection blood thinner when undergoing any procedure where cutting is a possibility.
From what I understand, the oral blood thinners suppress vitamin k, which is what makes blood clot well. But if you get clots, you want to suppress the vitamin K on a day-to-day basis.
The heparin and lovenox work differently by interfering with blood proteins. But they are shorter lasting and are better for short term use, like operations or tests that have a possibility of requiring cutting (endoscopy). But they're not good maintenance meds when you can take longer lasting meds that aren't a daily injection.
Another reason - lovenox and heparin can be reversed in emergency. Warfarin and the vitamin K suppressers are way harder to reverse.

I also have APS, but it's mild. I take acetylsalicylic acid 100mg.
I was reading and Lovenox is like heparin. Heparin is what I'm supposed to take before going on long airplane trips. It's strong.
I'm afraid I can't help you there, as I haven't have the need for a surgery/medical procedure since starting this treatment with blood thinners. Hope you find some answers. Hugs

I'll keep you in my prayers 🙏. Love and hugs

To MyCrazyLife - I'm laughing because that 1-2-3-GO is what I do with injectables. A nurse taught me. I actually cannot push the needle in without the 123GO mantra. I grab the belly fat, 123GO, push in needle, push plunger, done.
