Frequently Asked Questions

Why is the Bax-si different from other back pain relief devices?

Unlike other back pain relief devices, the Bax-si is the only device designed specifically to unlock the sacroiliac (SI) joints.  The gel wave heads gently open the SI joints to relieve pressure and pain in your lower back, buttocks, legs and feet.

Do I have to use the level 2 firmness gel in order to achieve back pain relief?

No.  Use the level 1 green gel wave head when you first start using the Bax-si.  Once you get comfortable using the green gel wave head try the blue gel wave head. If the pressure is too intense go back to using the green gel wave head.

Can multiple people use the device?

Yes. We purposefully created the device with two removable gel wave heads with different levels of firmness to allow multiple people with varying levels of pain tolerance to use the same device.

What is the Bax-si made of?

The Bax-si base is made of an injection molded PBT plastic material. The two gel wave heads are made of silicon.

What is the weight limit?

400 pounds weight limit.

Will the Bax-si work immediately?

You should feel less pressure in your back and your leg will feel lighter on the side you used the Bax-si. Use it on a regular basis to feel the full impact of pain relief.

Is it normal to feel a burning when using the Bax-si?

Yes, it is.  The burning is the releasing of tight ligaments and fascia around the SI joint. Burning is different to pain. This burning should reduce with ongoing pressure.  If the burning sensation becomes too uncomfortable move back to the previous position and work your way up to position four.

Should I move directly to the fourth position when I use the Bax-si?

Initially, you do not need to go through all four positions to feel relief. This is not a race. Using the Baxsi regularly will loosen up your sacroiliac allowing you to transition through all four positions.   If you never get to the fourth position do not worry.  You can get results from using it in any of the four positions.

Is it safe to use this device directly on my skin with no protective covering?

It is safe to place the device directly on your bare back unless you are allergic to silicon.   Please see next question for those allergic to silicon.

What if I am allergic to silicone?

Wear a thin shirt that covers your entire lower back so the gel wave head does not directly touch your skin.  Do not try to use this device while wearing jeans or pants with thicker material.  It will not work properly.  

Will insurance cover the purchase of this product?

The Bax-si has been designated an FSA and/or HSA eligible product by SIGIS (Special Interest Group for IIAS Standards).  Our payment methods should enable you to purchase the Bax-si with your FSA and/or HSA credit card.  If you have an issue with the purchase using your FSA/HSA credit card, you can submit a reimbursement request with your FSA/HSA claims administrator.
