From the Guidelines
The patient should be referred to a neurologist for evaluation of possible ulnar nerve compression or cervical radiculopathy, and undergo nerve conduction studies and electromyography (EMG) to assess nerve function and localize the compression site, rather than proceeding with a steroid injection. The current medication regimen of Meloxicam and Venlafaxine is not specifically targeting nerve compression, which explains the persistent symptoms. According to the guidelines for the pharmacological management of neuropathic pain 1, the next step would be to reassess pain and health-related quality of life frequently, and consider adding a medication more specific for neuropathic pain.
Some key points to consider in the management of this patient include:
- The patient's symptoms have persisted despite treatment with Meloxicam and Venlafaxine, suggesting the need for a re-evaluation of the treatment plan.
- The patient is already taking Venlafaxine, which has some effect on neuropathic pain, but may be insufficient alone 1.
- Gabapentin or pregabalin could be considered as add-on therapies, as they have been shown to be effective in the treatment of neuropathic pain 1.
- A recent guideline by the American Academy of Neurology recommends that the initial treatment of pain should also focus on the concurrent treatment of both sleep and mood disorders, as these are common comorbidities in patients with neuropathic pain 1.
While the patient has requested a steroid injection, the evidence suggests that this may not be the most effective next step, and that a more comprehensive evaluation and treatment plan may be necessary to address the underlying cause of the patient's symptoms. The patient's request for a steroid injection should be balanced against the potential risks and benefits of this treatment, and the need for a more thorough evaluation of the patient's condition.
In terms of specific medications, gabapentin or pregabalin could be considered as add-on therapies, starting at low doses and gradually increasing as needed and tolerated. For example, gabapentin could be started at 300mg at bedtime and gradually increased, or pregabalin could be started at 75mg twice daily. The patient should be closely monitored for response to treatment and potential side effects.
From the Research
Patient Management
The patient is experiencing persistent tingling and numbness in the left fourth and fifth digits despite being on Meloxicam 2 and Venlafaxine, and having tried Voltaren (Diclofenac) gel. The next step for this patient would be to consider alternative treatment options.
Treatment Options
- Steroid injection in the ulnar nerve: This option is being considered for the patient, as they have already tried other medications without relief.
- Other treatments for neuropathic pain: According to the 2024 study on neuropathic pain 3, other treatment options for neuropathic pain include gabapentin, tricyclic antidepressants, topical lidocaine, and transcutaneous electrical nerve stimulation.
- Peripheral nerve blocks: A 2022 study on complex regional pain syndrome 4 found that peripheral nerve blocks along with intra-articular steroid injection can be an effective method of management for upper limb pain.
Rationale for Steroid Injection
- The patient has already tried Meloxicam 2, a nonsteroidal anti-inflammatory drug (NSAID), without relief.
- Venlafaxine, an SNRI, may be providing some neuropathic pain coverage, but the patient is still experiencing symptoms.
- The patient has also tried Voltaren (Diclofenac) gel without relief, suggesting that alternative treatments such as steroid injection may be necessary.
- The 2022 study on complex regional pain syndrome 4 provides evidence for the effectiveness of peripheral nerve blocks, including ulnar nerve blocks, in managing upper limb pain.
