Medical Uses of Muscle-Relaxing Injections & PRP in London
Most people hear about muscle-relaxing injections and “PRP” and think aesthetic treatments. It’s true that both of these techniques are used for smoothing wrinkles and anti-ageing. We can’t ever forget Kim K’s “vampire facial”, which was many people’s introduction to PRP!
But did you know that in the right hands, these techniques can help with medical conditions too? Dr Eldimarys Curry-Machado is using these techniques to help patients improve their quality of life. From relieving chronic migraines and jaw clenching to managing joint pain and hair loss, Muscle-relaxing injections and PRP are proving their effectiveness beyond aesthetics. Here’s how these popular treatments are helping patients improve health, comfort, and quality of life.
Injections for Migraines
Chronic migraines are more than “bad headaches” — they can be debilitating, affecting work, family life, and wellbeing. When standard medications fail, muscle-relaxing injections have emerged as an effective medical treatment.
How it works
The injections work by blocking nerve signals to targeted muscles. In migraine patients, injections around the head and neck reduce muscle tension and disrupt the pain pathways that trigger headaches.
What the research shows
The NHS and NICE (National Institute for Health and Care Excellence) recognise these injections as a treatment for chronic migraine. Studies show it can reduce the frequency and severity of migraines, improving the quality of life for many sufferers.
Treatment at Harley Street Health Centre
Dr Curry-Machado will carefully map injection sites typically across the forehead, temples, back of the head, and neck. A full treatment takes 30 minutes, with results building gradually over weeks. Patients often notice fewer and less severe migraine attacks after the first two sessions.
Muscle-relaxing injections for TMJ, Jaw Clenching and Tightness
The jaw or temporomandibular joint (TMJ) is one of the most active joints in the body. For some people, stress or misalignment leads to chronic clenching or teeth grinding (bruxism), causing:
- Jaw pain and tightness
- Headaches
- Worn teeth
- Facial tension
How injections help
By injecting small amounts of muscle-relaxant into the masseter muscles (along the jawline), we can reduce overactivity. The muscles relax, easing pressure on the TMJ and relieving pain. Many patients also notice a softer jawline appearance, which can be a welcome cosmetic bonus.
Benefits
- Reduced pain and tension
- Fewer headaches related to clenching
- Improved sleep (less night-time grinding)
- Prevention of further dental wear
Treatment is quick, with minimal downtime. Relief often lasts 3–4 months before a top-up is needed.
PRP for Knee Pain and Joint Problems
Joint pain, particularly in the knees, is a common complaint among active individuals, athletes, and older patients. Conditions like osteoarthritis or sports injuries can limit mobility and reduce quality of life.
What is PRP?
PRP stands for Platelet-Rich Plasma. It’s derived from a patient’s own blood: a small sample is taken, spun in a centrifuge to isolate platelets, and then re-injected into the affected joint.
Platelets release growth factors that stimulate tissue repair, reduce inflammation, and encourage healing.
PRP for the knee
Clinical studies show PRP can help with:
- Reducing pain and stiffness in osteoarthritis
- Improving mobility and function
- Supporting healing after ligament or meniscus injuries
At Harley Street Health Centre, we offer PRP knee injections as part of a personalised plan. Many patients report gradual but meaningful improvements over weeks to months.
PRP for Hair Loss
Another highly effective medical use of PRP is in treating thinning hair and hair loss. Unlike cosmetic treatments that mask hair loss, PRP stimulates natural regrowth.
How it works
When injected into the scalp, PRP delivers growth factors directly to hair follicles. This prolongs the growth phase of the hair cycle, strengthens existing hair, and stimulates dormant follicles.
Who benefits?
- Men with early-stage male pattern baldness
- Women with thinning hair due to hormonal or stress-related causes
- Patients wanting to boost results after a hair transplant
PRP is most effective in early or moderate hair loss. Treatments are typically done in monthly sessions for 3–4 months, followed by maintenance every 6–12 months.
