Tips for excruciating sciatic pain?

Yep, basically targeted stretching/yoga and probably some well instructed pilates would help (a specialist studio where the instructors really know their *kitten* and have spent years qualifying). I get sciatic pain but keeping strong and properly stretching out the entire area, being mindful not to overstretch, mostly keeps me totally in check now.

I'm sorry you're going through this. I just wanted to say that a month with anything is not going to be long enough to determine if the therapy or chiro will ultimately aid with your pain. These things take time, lots of time. First you have to get through the acute pain time period, which is different for everyone. After my accident and sometimes flare ups it can take months just to get through the acute pain phase. Then its pain management and gradual, slow, strengthening. With always being ever vigilant not to do anything that might undo all the progress.

Some things that helped for me, over the years, use your own judgement....

Post car accident nothing was working (meds) prescribed by the doc. They prescribed something so expensive I couldn't afford them, and then it occurred to me I hadn't tried just plain old aspirin, and I did, and it helped. Taking it with a cup of coffee for the caffeine, multiplied and sped its effect. Once inflammation is down, chiro adjustments worked better.

Chrio and phys therapy should be working together, not separately IMO. If your chiro says everything is where it should be, the therapy should be working to teach you those exercises that will help KEEP everything where it should be. Sports massage, deep tissue, may help break up old scar tissue and relieve spasms. If neither seems to be working logically with you, its possible you may want a second or third opinion from different therapists and chiros. As well as an ortho. After my accident I didn't know any better and went to one chiro and therapist in the same office, to no avail 3 times a week for 3 months, it was the second month when I couldn't get off the table that they sent me for an MRI and discovered my bulging disc. They kept me on long enough until my auto insurance policy money ran out and then informed me of that and I stopped going.

Are you supplementing with magnesium? Mag supplements may help with spasming and inflammation, as well as turmeric and ginger supplements. I take 2 brands, Slo Mag and Doctors Best https://www.vitaminshoppe.com/p/doctor-best-high-absorption-100-chelated-magnesium-240-tablets/db-7013 that offer something like 3 or 4 different forms of magnesium, I take 2 of one brand in the AM and 2 of the other brand before bed.

MSM may help in the long term with recovery, I found this one the best https://www.amazon.com/Jarrow-Formulas-Strengthens-Joints-1000/dp/B0013OSJ7S?th=1 and just mix one tiny scoop of the powder in water AM and PM along with the magnesium.

The Mag may help with spasms right away, but all of these are long term supplements and may take a few days/weeks to gain full effect. But I believe they help with my, with the muscle/joint repair process.

The MRI will help locate the source of the pain, good luck, I know how you feel.

Yoga, specifically aerial yoga has helped many people that I advised on this issue.

Hanging upside down help decompress the joints/spine, stretch the muscles, and adds flexibility.

I'm really sorry to hear someone going through this much pain.I have sciatica too.Mainly in my left hip.I've had the kind of feelings your having.It will shoot down your leg,and hit your ankle etc..
I can only say what's helped me.First of all rest,and stretching.Sitting,and crossing the left leg over the right,and turning to open up the joint.Not a miracle,but it helps.
Anti-inflammatory NSAIDS like aspirin,and ibuprofen can help.But of course it can irritate some people's stomachs.

I don't go to Chiropractors.( I don't personally believe in their claims )
So I would consult with an MD who specializes in pain,and orthopedic issues.You may be able to find a pain clinic in your area.Sciatic pain is very common.

What has helped me personally is two main things;
Losing weight.I had been depressed after the death of a loved for years,and just kept eating too much rich food.I had to face up to my lousy habits,and cut out all the sweets I was eating.I've lowered my sugar intake specifically.Having too much belly fat was pulling on my back,and hips.I think that was the major cause of the chronic hip pain for me.The severity anyway.I do still have pain,but it's more manageable.No more debilitating nerve shooters.
Second-Weight lifting.I know this sounds hardcore.It really isn't.I've been weight training most of my life.I had stopped doing it regularly.I went back to it with dedication,and a sense of purpose.
Doing squats,deep knee bends with a weight,has really changed the way my hips function.They're looser,and far stronger.My glutes,and quads can take the strain now.It has made a huge difference in how my back,and hips feel.I can have pain.But I can do what I need to do.The lifting,and plenty of stretching afterwards is crucial.
I'm still lifting,and could still lose some more fat.So I hope it keeps getting better.

Unfortunately sciatic pain can put you through an awful time.It takes time to rest,and work out of it.I know how hard it is to bear it when it's at it's worst.Seeing a specialist in pain problems might be a good idea.
Best wishes.

The only things that seemed to work for me were losing a significant amount of weight and not sitting for too long.

Hi there - I feel your pain (literally). I have suffered with sciatica since I was pregnant with my now adult daughter. That's a long time! After losing over 100 lbs., I joined our local Sr. Center and signed up for a Long Yang Tai Chi class. This is the only thing that has ever helped me. I've gone to PT, chiropractor, and ortho doctors. I've been on high doses of pain meds, but none of them relieved my sciatica like this form of Tai Chi. I also give a lot of due credit to the instructor. He's awesome! He's been studying Tai Chi and Chinese medicine for over 25 yrs. and has given me many stretches and tips to help alleviate symptoms. Thank God I have not had a sciatica episode since before last August when I began taking his class. And as noted above in some other comments, yoga stretches are helpful too. One important thing: check with your doctor BEFORE trying anything new. Peace.

YOGA!! My yoga instructor is always telling us which poses are great for sciatic pain. Hope that helps!!

I feel for you. I deal with chronic pain as well. I don't really have much advice, i just hope your pain eases soon.
Personally, yoga and stretching work amazingly for me.
Good luck to you.
