Conditions Piriformis syndrome

Conditions we treat

Piriformis syndrome

Deep buttock pain that can run down the leg, caused by a tight piriformis muscle pressing on the sciatic nerve.

Hip

What it feels like

You will usually feel this around the hip, groin, or outer thigh — often when you put on socks, get up from a low chair, climb stairs, or lie on that side at night. Walking distances tends to shrink as the pain builds. Some people describe a deep ache that is hard to point to with one finger.

How we approach it at our clinic

Wherever possible, we start with the least invasive option that has good evidence — and we use live image guidance (ultrasound or fluoroscopy) for any injection so the medication goes exactly where it needs to. Many of the procedures we offer for this condition are OHIP-covered when ordered for an appropriate clinical reason; we will be straight with you about what is and what is not before you book.

Procedures

Procedures we use for Piriformis syndrome

These are the procedures we most commonly use for the hip area. The right one depends on your imaging, history, and what has helped before.

Cortisone Joint Injection

✓ OHIP

A steroid injection placed directly into a joint to settle arthritis pain or inflammation. Works for shoulders, knees, hips, elbows, wrists, ankles, and the smaller joints of the fingers and toes.

Hip Joint Injection

✓ OHIP

A precise injection of long-acting anti-inflammatory medication into the hip joint. Used for hip arthritis pain that has not settled with physiotherapy and activity modification — typically 4–12 weeks of relief.

Hyaluronic Acid Injection

Not OHIP

A gel-like injection that supplements the natural lubricant in your joint. Often used for knee or hip arthritis when steroid injections have stopped giving you the relief they used to.

Peripheral Nerve Block Injection

✓ OHIP

An injection that targets a specific nerve outside the spine — for example, the occipital nerve at the base of the skull, or the suprascapular nerve at the shoulder. Calms the nerve that is feeding your pain.

Platelet Lysate Injection

Not OHIP

A regenerative injection using a processed form of your own platelets in which the healing growth factors are released up front. We typically consider this for nerve-related and tendon pain where a gentler regenerative option is preferred.

Homepage Portfolio

Not OHIP

A regenerative injection that uses the healing factors from your own blood to settle hip pain — typically offered for hip osteoarthritis or gluteal tendon pain when other injections have lost their effect.

Sacroiliac (SI) Joint Injection

✓ OHIP

A fluoroscopy-guided steroid injection into the sacroiliac joint. Used for one-sided buttock or low-back pain caused by SI joint dysfunction or sacroiliitis. Both diagnostic and therapeutic in one visit — typically 6–12 weeks of relief.
