Two readers in England sought help from Dr. Scurr after years of lingering nerve pain and alarming brain‑scan results. June Bunn, 71, from Staffordshire battles post‑herpetic neuralgia that makes her scracth herself awake, while Ruth Taylor, 77, of St Helens fears that MRI‑reported atrophy and ischemia signal an imminent stroke or dementia.

June Bunn’s 9‑year post‑herpetic itch cycle

According to the source, Bunn’s shingles episode nine years ago left her with chronic itchnig and neuropathic pain that persists despite pregabalin and amitriptyline. Dr.. Scurr explains that aging skin loses barrier function, so each night‑time scratch further irritates already damaged nerves, creating a self‑reinforcing loop.

Lidocaine patch vs. capsaicin: two OTC routes for nerve pain

Dr.. Scurr recommends a 4 % lidocaine medicated patch applied nightly for a month to numb the affected area, noting that the patch’s local anesthetic action can break the itch‑scratch cycle. If the patch fails, he suggests switching to a capsaicin cream or patch, which works by desensitizing nerve fibres over time. Both options are available without prescription, giving Bunn a practical first step while she discusses possible medication tweaks with her GP.

Ruth Taylor’s Grade 3 ischemia and stroke‑risk plan

The source states that Taylor’s MRI showed Grade 1 brain atrophy—normal for her age—and Grade 3 white‑matter ischemia, a sign of small‑vessel disease linked to hypertension, diabetes, smoking and age. Dr. scurr urges aggressive risk‑factor control : blood‑pressure and cholesterol management, possibly with statins and antiplatelet therapy, plus daily aerobic exercise that raises heart rate and leaves her slightly breathless.

Why mild brain atrophy is age‑appropriate, not a diagnosis

Dr. Scurr reassures that mild atrophy alone does not constitute a disease; it reflects normal brain‑volume loss after the seventh decade. The real concern lies in the moderate ischemic changes, which can be mitigated by a Mediterranean diet rich in olive oil, vegetables, fruits, legumes, nuts and whole grains.

What further testing might clarify Ruth’s vascular health?

The column leaves unanswered whether Taylor should undergo carotid‑ultrasound screening or a cardiac work‑up to pinpoint the source of her small‑vessel disease. As the source notes,only a full clinical assessment can determine if additional imaging or blood‑marker tests are warranted.
