How to recognize a tick under the skin and act quickly
A tick bite can sometimes leave a small parasite under the skin, often imperceptible at first. This tiny creature, common in forests or tall grass, attaches itself to the skin to feed on blood. In France, more than 40,000 cases of Lyme disease are detected each year, an infection transmitted by ticks carrying the Borrelia burgdorferi bacteria. A tick bite usually goes unnoticed because it is painless, which requires particular vigilance when outdoors. As soon as a red rash appears that spreads around the bite, called erythema migrans, an urgent medical consultation is necessary. Always inspect your body and scalp after a walk in nature, especially skin folds and delicate areas. If you detect a tick, you must remove it immediately to reduce the risk of tick-borne infection. Use a tick remover or fine tweezers to grasp the tick as close to the skin as possible. Safe techniques for removing a tick and avoiding complications
The recommended method for removing a tickis to grasp it gently as close to the skin as possible and slowly twist it to detach it, without squeezing its abdomen, which could release bacteria into the body. Afterward, it is essential to disinfect the area with a suitable antiseptic to limit the risk of secondary infection.
- In some cases, part of the tick—the hypostome, the mouthparts embedded in the skin—may remain stuck. This situation no longer poses a direct risk of Lyme disease transmission
- because the bacteria are located in the salivary glands or the abdomen, which have already been removed. Use fine forceps or a sterile needle to extract any visible fragments.For ticks embedded too deep, allow them to dissolve naturally while monitoring the area.Watch for signs of local inflammation: redness, pain, or swelling.
- Symptoms to watch for after a tick bite under the skin
After a bite, it is crucial to remain vigilant for a month to detect any symptoms suggestive of a
tick infection or progression to Lyme disease . The first telltale sign is often a progressively spreading red rash around the bite. In addition to erythema migrans, other symptoms may appear:
fever, headache, and intense fatigue, signs of the flu; persistent joint pain; neurological problems such as numbness or cognitive impairment.
- These symptoms absolutely require a
- prompt medical consultation
- in order to implement appropriate treatment.
Medical Treatment of Lyme Disease in 2025 When Lyme disease is diagnosed early, a cure is effective thanks to antibiotic treatment prescribed by a doctor. The most common protocols in 2025 include: a course of doxycycline or amoxicillin for 14 to 21 days; in cases of severe involvement (nerve or joint problems), prolonged antibiotic therapy, sometimes intravenous;multidisciplinary medical follow-up when chronic symptoms persist.
It is crucial never to interrupt treatment without medical advice, even if the initial symptoms disappear. No human vaccine against ticks is yet available, highlighting the importance of tick prevention.
- What to do if the tick remains partially embedded in the skin?
- It is common for a small fragment of the tick to remain embedded in the skin, despite all precautions.
After removal, this situation may seem alarming, but it does not pose a major risk of pathogen transmission. However, these fragments can cause a local inflammatory reaction. Current recommendations for managing this situation are as follows: remove accessible fragments with disinfected tools;
do not force the foreign body if it is deeply embedded;
monitor for signs of inflammation over several weeks; consult a doctor if persistent pain, swelling, or a red spot develops. A real-life case, that of Florence, highlights how crucial early medical intervention is in preventing complications and disability in some severe cases.
