Peripheral Nerve Injections in Sharjah

What are peripheral nerve injections?

A peripheral nerve injection is a small, targeted injection of local anaesthetic, often combined with a steroid, placed beside a single nerve in the arm, leg, trunk or scalp where that nerve is trapped or irritated. Ultrasound guidance lets the doctor see the nerve on screen and lay the medicine alongside it through a fine needle.

The injection has two jobs, and each part of the mixture does one of them. The local anaesthetic numbs the nerve within minutes and wears off later the same day; if your usual pain disappears during those hours, that nerve is very likely the source. The steroid works more slowly, calming swelling and irritation around the nerve over the following days, and its effect can last considerably longer.

Peripheral nerve injections are sometimes confused with the nerve block procedures given by the anaesthesia team. A surgical nerve block numbs a whole limb for an operation. A peripheral nerve injection treats one troublesome nerve in clinic, as both a test and a treatment, and you stay alert to report how the pain changes. At Dar Al Kamal Hospital, Sharjah, these injections are offered by the neurosurgeon of the Neurosurgery department as part of its peripheral nerve work.

Who needs it

Peripheral nerve injections suit people whose pain, tingling or burning follows the map of one nerve, where the examination points to a specific spot along its route. Common targets include:

• The median nerve at the wrist, in carpal tunnel syndrome, to settle night-time tingling or to confirm the diagnosis before carpal tunnel release
• The ulnar nerve at the elbow or wrist, which affects the ring and little fingers
• The lateral femoral cutaneous nerve at the front of the hip, the cause of burning over the outer thigh in meralgia paraesthetica
• The greater occipital nerve at the back of the head, which can drive a sharp, shooting headache from the base of the skull over the scalp, known as occipital neuralgia
• Small skin nerves caught in a scar after an earlier operation

An injection often sits between simple measures, such as splints, changes in posture or clothing and anti-inflammatory tablets, and an operation. For some people it settles symptoms enough to make surgery unnecessary. For others, the answer it gives helps the surgeon choose exactly which nerve to release. A nerve conduction study is often done first, so the injection targets a confirmed site.

What happens

The injection is an outpatient procedure and you stay awake throughout. You sit or lie in a position that opens up the area: the arm resting on a pillow for the wrist or elbow, lying on your back for the thigh, or sitting and leaning forward for the back of the head.

1. The doctor scans the area with ultrasound to find the nerve and the structures around it.
2. The skin is cleaned with antiseptic. For the occipital nerve, the hair is parted over the spot, and shaving is rarely needed.
3. A fine needle is guided beside the nerve while the doctor watches its tip on screen. You may feel a brief sting, then a tingle or pressure spreading along the nerve's path, which tells the doctor the needle is close.
4. The medicine is injected slowly and a small plaster is applied.

Before you leave, you try the movements that normally bring on your pain and note how they feel.

Preparing for it

Eat and drink as usual beforehand unless you are told otherwise. Tell the team if you take blood thinners, have diabetes, have reacted to a local anaesthetic or steroid in the past, or might be pregnant. People with diabetes should bring their glucose meter, because a steroid injection can raise blood sugar for a few days and readings are worth checking more often.

Keep a simple daily pain score for the week before, so the change after the injection is easy to judge. Wear clothing that uncovers the area easily: a short-sleeved top for arm injections, loose trousers for the thigh. For a hand or arm injection, arrange for someone to drive you home, since the numbness can weaken your grip on the steering wheel for some hours. During Ramadan, ask the team about a time that suits your fast when you book.

Afterwards

The area may feel numb or heavy for some hours while the local anaesthetic is active. Record your pain every few hours for the rest of that day: this pain diary is part of the test, and the doctor uses it to judge whether the injected nerve is the true source. Some people feel extra soreness for a day or two before the steroid begins to work, and a cool pack helps.

Protect a numb hand or foot from heat until feeling returns, because hot car door handles, seatbelt buckles and cooking pans in the Sharjah summer can burn skin that feels nothing. Keep the plaster on and the site dry for the first day. Desk work can usually resume the next day, and the doctor advises on driving and manual work. At follow-up, the doctor reviews your relief and plans the next step: another injection, physiotherapy, or an operation described on the peripheral nerve surgery page.

Contact the hospital if the injection site becomes red, hot, swollen or leaks, if you develop a fever, or if numbness or weakness lasts beyond the day of the injection or gets worse.

Cost and insurance

Most UAE insurance plans cover peripheral nerve injections when they are medically needed. Many insurers ask for pre-approval supported by the clinical findings and, often, a nerve conduction report. Repeat injections at the same site are sometimes reviewed separately, and some plans limit how many are approved in a year.
