Postherpetic neuralgia
Dear Doctor,
1.
My father had shingles on his left chest three years ago, and since then he has been suffering from postherpetic neuralgia.
What are some effective treatments for this condition?
2.
My father has a bowel movement once after breakfast, which is generally normal, although sometimes it can be a bit hard.
However, shortly after, he experiences another urge and passes yellow, clay-like stools, totaling about four times a day.
What could be the cause, and how can it be treated?
Additionally, my father has been experiencing dizziness and headaches for a long time and is currently taking Xanax and Ativan 0.5 mg before bedtime.
Thank you for your time and assistance.
We are very grateful!

Hello DEER sp310386:
1.
Postherpetic neuralgia resulting from shingles is difficult to treat.
Generally, acupuncture at the nerve ganglia, combined with medications, especially certain antiparasitic drugs, is used to alleviate pain.
2.
The two medications your father is taking are both classified as "sedatives," and they should not be related to the consistency of his stool.
Please check if he is also taking an additional dose of MgO, as this medication is a laxative and can cause softer stools.

More Info
Postherpetic neuralgia (PHN) is a common complication following herpes zoster (shingles), characterized by persistent pain in the area where the shingles rash occurred. The pain can be debilitating and significantly affect the quality of life. In your father's case, having experienced shingles three years ago, it is not uncommon for him to still suffer from this condition.
Effective Remedies for Postherpetic Neuralgia
1. Medications:
- Gabapentin (Neurontin) and Pregabalin (Lyrica) are first-line treatments for neuropathic pain, including PHN. They work by modulating the release of neurotransmitters and reducing the excitability of neurons.
- Antidepressants: Tricyclic antidepressants (like amitriptyline) can also be effective in managing neuropathic pain. They help by altering the way the brain perceives pain.
- Topical Treatments: Lidocaine patches or capsaicin cream can provide localized relief. Lidocaine works by numbing the area, while capsaicin depletes substance P, a neurotransmitter involved in pain signaling.
2. Physical Therapy: Engaging in physical therapy can help improve function and reduce pain. Techniques may include gentle stretching, strengthening exercises, and modalities like heat or cold therapy.
3. Alternative Therapies:
- Acupuncture has shown promise in some studies for alleviating neuropathic pain.
- Transcutaneous Electrical Nerve Stimulation (TENS) may provide relief by stimulating nerves and potentially altering pain perception.
4. Pain Management Clinics: If the pain is severe and unresponsive to standard treatments, referral to a pain management specialist may be beneficial. They can offer advanced treatments such as nerve blocks or spinal cord stimulation.
Addressing Digestive Issues
Regarding your father's digestive symptoms, the pattern of bowel movements you described—normal in the morning but then experiencing loose stools—could indicate several underlying issues:
1. Dietary Factors: It’s essential to evaluate his diet. High-fat or high-fiber foods can sometimes lead to changes in bowel habits. Keeping a food diary may help identify any triggers.
2. Medication Side Effects: Xanax (alprazolam) and Ativan (lorazepam) can affect gastrointestinal motility. If he has been on these medications for an extended period, it might be worth discussing with his physician whether they could be contributing to his digestive issues.
3. Gastrointestinal Disorders: Conditions such as irritable bowel syndrome (IBS) or infections can cause changes in bowel habits. A gastroenterologist can perform tests to rule out these conditions.
4. Hydration and Fiber: Ensuring adequate hydration and a balanced intake of dietary fiber can help regulate bowel movements. If he experiences hard stools, increasing fiber intake gradually can be beneficial.
5. Probiotics: These can help restore gut flora balance, especially if he has had any recent antibiotic use or gastrointestinal disturbances.
Conclusion
In summary, for your father's postherpetic neuralgia, a combination of medications, physical therapy, and possibly alternative treatments should be considered. For his digestive issues, a thorough evaluation by a healthcare provider is essential to rule out any underlying conditions and to adjust his medications if necessary. It’s crucial to maintain open communication with his healthcare team to tailor a treatment plan that addresses both his pain and digestive concerns effectively.
