What if you’ve been treated for plantar fasciitis, but your heel still hurts?
I’ve evaluated patients whose foot pain persisted despite stretching, orthotics, physical therapy, and even injections.
Sometimes nerve problems, inflammation, or another medical condition may be contributing.
When heel pain occurs alongside fatigue, migrating joint pain, or neurologic symptoms, Lyme disease may be one consideration.
Heel pain alone cannot diagnose Lyme disease.

In my practice, I have evaluated patients with Lyme disease who describe cold, mottled, red, or purple extremities along with dizziness, palpitations, temperature intolerance, or other symptoms suggesting autonomic dysfunction.

What can cause the hands to turn red and purple?

Why do hands turn red or purple? Explore Raynaud's, blood pooling, autonomic dysfunction, and other causes of color changes.

Can you have pressure behind your eyes even when your eye examination is normal?
Yes. The sensation of pressure doesn’t necessarily mean elevated pressure inside the eye.
Migraine, dry eye, inflammation, and neurologic conditions can contribute.
In my Lyme disease practice, some patients also describe eye pressure alongside headaches, dizziness, or light sensitivity. These symptoms are not specific to Lyme disease.
Sudden vision changes or severe eye pain require urgent evaluation.

Lyme disease can affect the nervous system, causing a range of neurological symptoms, including numbness, tingling, shooting pain, and muscle weakness.

When Lyme disease affects the peripheral nerves or nerve roots, the resulting pain can feel electrical, stabbing, or like lightning shooting through the body.

Have you experienced electric-shock sensations from Lyme disease?

Why are electric-shock sensations hard to explain? Learn why sudden nerve jolts are difficult to describe and may evade routine tests.

Why do some patients feel worse the day after exercise?
I’ve seen patients complete a short walk or household activity, only to experience increased fatigue, pain, brain fog, or dizziness the following day.
This delayed worsening may reflect post-exertional malaise.
I’ve encountered this pattern in patients with persistent symptoms following Lyme disease and other chronic illnesses.
I ask patients how they feel after activity, including the next day.
But I also encourage them to continue working toward recovery.
That may mean adjusting activity, allowing more recovery time, or finding smaller amounts of movement they can tolerate without repeatedly triggering flares.

She was walking her dog. The next day she developed what doctors' believed was a spider bite.

Severe pain spread through the joints of her left hand, wrist, elbow and shoulder. Swelling and stiffness became so debilitating that she developed what she described as a frozen shoulder and elbow. She developed fatigue and cognitive problems.

It took 9 months before she was correctly diagnosed with Lyme disease.

'My body felt old, stiff, like someone was pouring mortar into my veins,' Sadie Bridgeman says of debilitating symptoms as tick encounters increase across Ontario

Ever wonder why your brain fog is worse in the morning?

Some people wake up with such severe brain fog that they struggle to think clearly, find words, remember what they need to do, or begin their usual morning routine.

Why is brain fog worse in the morning? Explore sleep inertia, sleep apnea, autonomic dysfunction, and clues in symptom timing.

Can Babesia appear after Lyme disease treatment?
A 67-year-old woman developed a fever approaching 103°F near the end of treatment for Lyme disease.
Her red blood cells, white blood cells, and platelets were low. Further testing confirmed Babesia.
She improved after receiving atovaquone and azithromycin.
The important distinction: Amoxicillin treats Lyme disease but not Babesia. Both infections may be transmitted by the same tick.
New fever and abnormal blood counts during Lyme treatment warrant prompt evaluation.
