Why does it hurt more after applying a topical ointment following a stiff neck?

Generally, applying plasters after a stiff neck may paradoxically cause more pain, possibly due to factors such as the time required for the medication to take effect, incorrect use of the medication, allergic reactions, neuropathic pain, or bacterial infection. If discomfort occurs, timely medical attention is recommended. Detailed explanations are as follows:

1. Time Required for Medication to Take Effect

Medication usually takes some time to work, and the pain caused by a stiff neck might worsen during this period, leading to increased pain after applying plasters. This is a normal phenomenon, and patients can patiently wait for the medication to take effect.

2. Incorrect Use of Medication

If the plaster is not applied correctly after a stiff neck—for example, applying it to the wrong location or leaving it on too long—it may lead to excessive muscle stimulation and inflammatory reactions, causing increased pain after applying the plaster. It is recommended to carefully read the instructions and apply the plaster correctly as directed.

3. Allergic Reaction

If an individual is allergic to certain components in the plaster, symptoms of the stiff neck may worsen after application, causing increased pain. This is often accompanied by symptoms such as redness, swelling, and itching of the skin. It is recommended to follow medical advice and use medications such as Levocetirizine Hydrochloride Tablets, Mizolastine Sustained-release Tablets, or Setastine Hydrochloride Tablets for treatment.

4. Neuropathic Pain

A stiff neck may damage the cervical nerves, causing neuropathic pain. Applying plasters may irritate the damaged nerves, resulting in increased pain after plaster application. This is usually accompanied by symptoms such as stabbing pain and numbness. It is recommended to use medications such as Aspirin Sustained-release Tablets, Paracetamol Tablets, or Ibuprofen Sustained-release Capsules under a doctor's guidance.

5. Bacterial Infection

If there are minor skin injuries or open wounds at the site where the plaster is applied after a stiff neck, bacterial infection may occur. The application of plasters may exacerbate the inflammatory response, causing increased pain after plaster use, accompanied by symptoms such as exudation and fever. It is recommended to use medications such as Amoxicillin Capsules, Clarithromycin Capsules, or Metronidazole Tablets under medical supervision to control the infection.

It is important to maintain personal hygiene, bathe regularly, and change clothes to help prevent diseases.
