Thoracic outlet syndrome (TOS) remains one of the underdiagnosed conditions due to the unavailability of specific tests. The pain of TOS may mimic shoulder pain and or cervical radicular pain. Understanding the pathology and type of TOS is the key to successful management. Although surgery remains the final permanent solution in a conformed case of TOS, conservative therapies do provide great relief from pain. Botox remains one of the modalities in managing TOS pain by relieving the spasm of the scalene group of muscles and thereby alleviating the compression symptoms.

We report here to draw attention to an uncommon complication that could arise from routinely performed procedure in pain practice such as percutaneous trigeminal radiofrequency ablation (RFA). We report a case of a 53-year-old female who underwent trigeminal nerve RFA for trigeminal neuralgia. RFA after adequate assessment with sensory and motor stimulation is performed as a routine procedure followed by 0.2 ml 1% lignocaine for dense sensory block at the target, following which the patient developed giddiness, nausea, vomiting, and nystagmus. After 2 h of rest and gaze fixation, her symptoms improved, with a decline in the severity of nystagmus. Symptoms gradually resolved over a period of 3 h. Proximity of the membranous part of the auditory tube to the foramen ovale might lead to such mishaps. Direct administration of 1% lignocaine into the middle ear via the auditory tube might be the most likely reason for her condition.

Traumatic neuromas are sometimes formed in the surgical scars. Peripheral nerve injuries lead to complex clinical presentation. They are benign tumors which are formed by critical nerve tissue interaction and are extremely painful. They are formed by intraneural or extraneural scar formation affecting the nerve-gliding plane. Their main clinical presentation is neuropathic pain. This condition is also termed as “painful scar neuropathy.” There have been different approaches to treatment depending on the type of lesion whether it is perineural, endoneurial, or combined and type of pain due to traction or trauma, rest pain, and severity. Varying degrees of therapeutic success has been described in literature using different techniques. There is no consensus on the best therapeutic approach to treat neuropathic pain due to scar tethering. Patient counseling about the condition and the need for multiple interventions, if needed, is essential. Here, we report a case of a 16-year-old female with traumatic neuroma of superficial peroneal nerve formed in the surgical scar of chronic osteomyelitis presenting with severe pain and paresthesia treated by pulsed radio frequency (PRF). PRF is a novel therapeutic method to treat many conditions in pain medicine as it offers treatment without motor deficits and deafferentation syndrome.

Osteoarthritis of the first carpometacarpal joint also called as trapeziometacarpal joint is the most common of all five carpometacarpal joints to undergo degeneration. The patient suffers with chronic pain, tenderness, stiffness of joint, and sometimes, even deformity can be seen in long-standing cases. Due to limited treatment options, patients have to suffer with side effects of pain killers or may have to undergo surgical intervention, but intra-articular joint injections and platelet-rich plasma therapy have been proven efficacious in providing good pain relief.

Vulvodynia is a condition of considerable vulvar pain and discomfort to women which affects approximately 16% of women and is mostly not diagnosed. The patients are rarely treated. The patients mostly consult gynecologist and as they do not present with any local signs are treated with antibiotics and analgesics only. The cause of vulvodynia is not known, so there is no known effective treatment available. The patients' symptoms and literature suggest it be neuropathic in origin. A ganglion impar block was used in this patient which was effective in treating the patient.

We at Our Pain Clinic witnessed a rare event of recurrent bradycardia and hypotension during radiofrequency ablation of mandibular division of trigeminal nerve. A 48-year-old lady with trigeminal neuralgia in left V3 distribution was posted for V3 division rhizotomy under fluoroscopy. The patient had transient episodes of bradycardia and hypotension during the procedure. The patient had transient episodes of bradycardia and hypotension during the procedure. HR and BP were reverted to baseline with injection atropine and intravenous fluids. This response is most likely attributed to trigemino cardiac reflex, which occurs due to inadvertent stimulation of trigeminal nerve.

Cervical epidural steroid injection is an intervention done for cervical prolapsed intervertebral disc. Cervical epidural steroid injection is done if a patient has not responded to medications and physical therapy. We discuss a case report of the occurrence of Horner's syndrome in the patient with cervical radiculopathy undergoing cervical interlaminar epidural steroid injection which resolved spontaneously without residual side effects.
