Bruxism (Teeth Grinding and Jaw Clenching)

Bruxism means you grind or clench your teeth, often at night without noticing. Typical symptoms include tight or tired jaw muscles, morning headaches, worn or sensitive teeth, and sometimes pain around the ears or temples. Many people also notice disturbed sleep and their partner may hear grinding sounds.

Botulinum toxin injections for bruxism are usually given into the chewing muscles on each side of the face, most often the large muscle at the angle of the jaw (masseter) and sometimes the muscle at the temples (temporalis). The doctor uses several small injections in each muscle, spread out to cover the area evenly. The treatment is quick and usually well tolerated; you may feel brief stings or pressure.

The medicine works by gently relaxing the overactive jaw muscles. You should still be able to chew and speak normally, but the extreme clenching force is reduced. Over the next few weeks, many patients notice less jaw pain, fewer morning headaches, and better sleep. Teeth grinding sounds often become much quieter or stop completely.

The effect usually starts within a few days, with the full benefit often felt after 2–4 weeks. For most people, the improvement lasts around 3–4 months, sometimes longer. When the effect wears off, the muscle activity slowly returns. Treatments can usually be repeated about 2–4 times per year, depending on how long the benefit lasts for you and how strong your symptoms are.

Excessive Sweating (Hyperhidrosis)

Excessive sweating means you sweat much more than is normal for the temperature or your activity level. Typical symptoms include wet patches on clothes, sweat dripping from the underarms, hands, feet, or face, and needing to change clothes or use strong antiperspirants often. It can be embarrassing and may affect work, social life, and confidence.

Botulinum toxin injections for sweating are usually given directly into the skin of the problem area, such as the underarms, palms, soles. The doctor marks the area and gives many tiny injections in a grid pattern a few millimetres apart. This helps cover the whole sweating zone. The needles are very fine; you may feel brief stings or burning, but the procedure is usually quick. For sensitive areas like the palms, a numbing cream or other pain relief may be used.

The medicine works by blocking the nerve signals that tell the sweat glands to produce sweat. It does not affect your overall ability to cool down, because only a small area is treated. Most people notice that the treated area becomes much drier, with far fewer or no visible sweat patches. This can make daily life more comfortable: clothes stay dry longer, handshakes feel easier, and you may feel less need to plan your day around sweating.

The effect usually begins within a few days, with the full result after about 1–2 weeks. For many patients, the benefit lasts around 4–7 months in the underarms and often a bit less on the hands or feet. When sweating slowly returns, the treatment can be repeated, usually 1–3 times per year, depending on your symptoms and how much dryness you want to maintain.

Chronic Migraine

Chronic migraine means you have headaches on many days of the month, with at least some of them having typical migraine features such as throbbing pain, nausea, sensitivity to light or sound, and difficulty concentrating. Many people feel they are always recovering from the last headache or waiting for the next one. This can affect work, family life, and sleep.

Botulinum toxin for chronic migraine is given as a series of small injections in specific spots across the forehead, temples, back of the head, neck, and shoulders. The doctor follows a standard pattern, usually with several dozen tiny injections in total, spread over both sides. The needles are very fine, and each injection is quick. You may feel brief stings or pressure, but most people tolerate the procedure well and can go home or back to work soon after.

The goal of treatment is not to remove every single headache, but to reduce how often and how severe your migraines are. Many patients notice fewer migraine days per month, milder attacks, and less need for pain medication. This can mean more good days, better sleep, and more freedom to plan daily activities without constant fear of a severe attack.

The effect usually starts to build over the first few weeks, with clearer changes often seen after the second treatment cycle. For chronic migraine, injections are commonly repeated every 12 weeks (about every 3 months). It may take 2–3 treatment rounds to see the full benefit. If the treatment works well, your doctor may suggest continuing on this schedule to keep the number of migraine days lower over time.

With all these treatments, it is important to have realistic expectations and to discuss your personal situation with your doctor. Botulinum toxin does not cure the underlying condition, but it can make daily life more manageable by reducing pain, improving sleep, and lowering the impact of symptoms on your work, relationships, and overall well-being.
