An X-ray shows bone. Your pain probably isn't coming from bone.

Most foot and ankle pain originates in soft tissue — the tendons, ligaments, nerves, fascia, and bursae that an X-ray simply cannot see. That's why patients so often leave an appointment having been told their X-ray looked fine, still in pain, and still without an explanation.

Diagnostic ultrasound solves that problem. At Bayshore Podiatry Center, Dr. James E. Repko, DPM, DABPM and Dr. Saleena Niehaus, DPM, DABPM perform and interpret musculoskeletal ultrasound in our South Tampa office, giving you a real answer during the same visit you came in for.

What makes ultrasound different

The structures we're imaging in the foot sit millimeters below the skin, and resolving them requires high-frequency imaging equipment specifically suited to superficial tissue. Ours produces resolution fine enough to measure individual tendon fibers — which is what allows ultrasound to answer, in the office, questions that would otherwise require an MRI.

It shows soft tissue. Tendon thickening, partial tears, fluid, nerve enlargement, and inflammation are all visible on ultrasound and invisible on X-ray.

It shows movement. This is the part MRI can't do. An MRI captures your foot lying still. Ultrasound lets us watch a tendon glide, load a ligament to test whether it's stable, and reproduce the exact motion that hurts — while we're looking at it. A tendon that appears intact at rest can reveal itself the moment it's put under load.

It's immediate. No referral, no imaging center, no waiting for a radiologist's report. We scan, we look, and we discuss what we're seeing before you leave.

It's completely safe. Zero radiation. Nothing injected. Nothing that rules you out — ultrasound is safe during pregnancy and safe for patients with pacemakers, metal implants, or claustrophobia, all of which can complicate an MRI.

It's dramatically less expensive. For many soft tissue problems, ultrasound answers the same question an MRI would, at a small fraction of the cost and without the prior-authorization delay.

You see it too. The screen faces you. When we point out the thickened, disorganized section of your plantar fascia next to the healthy tissue beside it, you're looking at your own foot. Patients understand their condition very differently after seeing it than after being told about it.

What we use ultrasound to diagnose

Heel and arch pain — measuring plantar fascia thickness and identifying tearing, fluid, or inflammation, and distinguishing plantar fasciitis from the other conditions that mimic it, including nerve entrapment and fat pad problems.

Tendon injuries — Achilles tendinopathy and rupture, peroneal tendon tears and subluxation, posterior tibial tendon dysfunction. Both the chronic degenerative changes and the acute tears.

Nerve conditions — Morton's neuroma, tarsal tunnel syndrome, and other nerve entrapments, seen as measurable enlargement of the nerve itself.

Ligament and sprain injuries — ankle ligament tears, syndesmotic injuries, and chronic instability, assessed under stress rather than at rest.

Inflammation and fluid — bursitis, synovitis, joint effusions, and ganglion cysts.

Gout and inflammatory arthritis — urate deposition produces characteristic findings on ultrasound, often visible before changes appear on X-ray.

Foreign bodies — splinters, glass, and other embedded objects, including the radiolucent ones an X-ray will never show. Ultrasound locates them and guides removal.

Soft tissue masses — identifying and characterizing lumps, cysts, and swellings, and determining which ones need further imaging or biopsy.

Ultrasound-guided treatment

Beyond diagnosis, ultrasound guidance meaningfully improves the treatments that follow it. Injections placed under direct visualization go into the intended tissue rather than approximately near it — which matters for accuracy, for comfort, and for whether the treatment works.

We use ultrasound guidance for corticosteroid injections, aspiration of cysts and fluid collections, and our regenerative treatments including PRP and prolotherapy.

What happens after the scan

The scan isn't the point. The plan is.

Once we've identified the specific structure generating your pain, we'll walk you through your options — including the conservative measures that cost you nothing and the treatments your insurance already covers. Then you'll get a clear recommendation and the reasoning behind it.

An accurate diagnosis is what makes a targeted treatment plan possible. Without it, treatment is guesswork, and guesswork is how people end up eighteen months into a problem that should have taken eight weeks.

Schedule an evaluation with our Tampa foot and ankle specialists

Persistent foot or ankle pain deserves a real answer, not a wait-and-see. If you've been told your X-ray was normal and you're still hurting, ultrasound is very often the study that finds what was missed.

Our South Tampa Medical Center office serves patients throughout Tampa Bay, including Hyde Park, Davis Islands, and MacDill Air Force Base. We offer flexible scheduling and same-day appointments for urgent conditions.

FAQs

Does a diagnostic ultrasound hurt? No. Warm gel is applied to the skin and a small probe is moved over the area. There are no needles and no discomfort beyond mild pressure. If the area is already tender, we work gently around it.

How long does it take? Most scans take about 10 to 15 minutes and are performed during your regular appointment. There's no separate visit and no separate facility.

Do I need a referral? No. You can schedule directly with our office.

Is there any radiation? None. Ultrasound uses sound waves, not radiation, which makes it safe to repeat as often as needed and safe during pregnancy.

When will I get my results? The same visit. Your podiatrist performs and interprets the scan in the room, so we discuss what we're seeing with you as we're seeing it — no radiologist report to wait on.

Ultrasound or MRI — which do I need? It depends on the question. Ultrasound is excellent for tendons, ligaments, nerves, fluid, and anything requiring assessment in motion, and it's faster and far less expensive. MRI is better for bone, deep structures, and complex or surgical planning cases. We'll tell you honestly if your situation calls for MRI instead.

Do I need to do anything to prepare? No preparation is required. Wear or bring clothing that allows access to your lower leg.
