Hi, Dennis-
I don't know what exactly you are taking for pain medication. IMO this is the time for Ibuprofen (Advil, Motrin, etc.). The key idea is 'anti-inflammatory', as Carbon Liberator mentioned. Now here's the deal- it turns out that for most lower back pain which is not spinal related (bad discs, etc.), the cause is simply poor abdominal muscle tone. Weak abdominals translate to greater forces on the back, and then those tiny back muscles start spasming and cramping and the pain can be quite intense. I can't tell what you have, but there is a good chance it is only muscle spasms, unless you have a known history of disc issues, etc. I once had it so bad I couldn't get up out of bed one morning. Finally resorted to finger walking my way up the wall to get standing, which took me like 10 minutes. Yikes! And it was just overexertion from a demolition job I had been doing. I have no disc issues.
If you are taking something stronger, well and good- but IMO taking an anti-inflammatory instead is very important. And in fact, it is important to HAMMER it (the muscle spasms) initially. Often one Ibuprofen is not enough for moderate to severe pain. Provided that there are no health risks in your particular case (talk to a doc), you'd best want to HAMMER it with about 3 of those 200mg tablets at a time. BTW you can buy 600mg Ibuprofen 'horse pills' as a prescription med. I have some of those. That constitutes PROOF POSITIVE that this can be done safely, theoretically under a doctor's supervision. I KNOW it's safe for most adult people in most cases (but check with your doc). In fact, my sister, who in her time knew this area *very* well indeed, told me that the max safe initial dose is actually 4 pills, that's 800mg at a time. Caveat emptor, YMMV, etc. I have done this on a few occasions and it was very effective for me. You don't want to do this for long, but you almost certainly can safely do this. There is a daily limit on the dosage but it is pretty high, actually- and you can exceed that for a short time. Just so long as you don't have any kidney issues. BTW there are those more frequent 'little blowouts' for which a double dose, 400mg, works just dandy. Repeat 2-3 times and then throttle back to one tablet every 4-6 hours. Never take on an empty stomach, you must have some food in there throughout the day.
The main thing is, if you know this will work for you and is not unsafe for you (true for most adults), Ibuprofen therapy is IMO about the best you can do. In fact, I'd do the Ibuprofen in preference to hydrocodone, codeine, percocets or whatever. Good pain pills all, but what you need usually is an anti-inflammatory. HAMMER it at the outset, and you will probably recover quick, then you can throttle back on the Ibuprofen very soon and taper back to one every 4-6 hours. My 2 cents...
Be well, my friend. Hope you have a speedy recovery.
