Red, Painful Skin: Possible Reactions to Allergy or Weather? - Dermatology

Red and painful skin?


I have been working in a meat processing plant in Australia, and I'm not sure if the symptoms I'm experiencing are related to the Qfevr test injection I received in my left arm.
There is a small red patch on my left arm that feels rough and slightly raised, with a painful sensation similar to an insect bite.
It hurts more when exposed to hot water, and this has been going on for three days without any improvement.
My right arm does not have any similar symptoms.
I'm unsure if this is due to the dry and cold weather in Australia or if it's related to the injection.
I would appreciate any advice.

Hello: It is not possible to accurately diagnose skin diseases based solely on a textual description.
Regarding Q fever vaccination, you can refer to the introduction on the Centers for Disease Control website at https://www.cdc.gov.tw/professional/info.aspx?treeid=4c19a0252bbef869&nowtreeid=4dc827595f55c334&tid=6EF26FFAA36DC9BD.
The text mentions that the Q fever vaccine for humans is currently only licensed in Australia and is primarily used for high-risk groups.
Additionally, individuals who have been exposed to the Q fever pathogen may experience severe allergic reactions if vaccinated, so relevant testing should be conducted prior to vaccination.
It is recommended that you return for a follow-up appointment to confirm whether there are any abnormal test results before proceeding with vaccination.
Thank you!

More Info


Based on your description, it seems that you are experiencing a localized skin reaction that could be attributed to several factors, including an allergic response, irritation from the Q fever test injection, or environmental conditions such as the dry and cold weather in Australia.
Firstly, it is important to consider the possibility of an allergic reaction to the Q fever test injection. Allergic reactions can manifest in various ways, including redness, swelling, and pain at the injection site. This type of reaction can occur shortly after the injection and may persist for several days. If the area is itchy or has developed a rash, it could indicate a hypersensitivity to the components of the vaccine or the needle itself.

Another potential cause for your symptoms could be contact dermatitis, which is an inflammation of the skin resulting from direct contact with an irritant or allergen. Given that you work in a meat processing plant, exposure to various substances, including chemicals or even certain proteins, could trigger such a reaction. The rough and painful texture you described may be indicative of irritation or an inflammatory response.

Additionally, the dry and cold weather in Australia can exacerbate skin conditions. Cold weather often leads to dry skin, which can become itchy and irritated. If your skin is already sensitive, the combination of cold air and potential allergens could lead to the symptoms you are experiencing.
To address your concerns, here are some recommendations:
1. Avoid Irritants: Try to identify any potential irritants in your work environment. If you suspect that certain substances may be causing your symptoms, consider wearing protective clothing or gloves.

2. Moisturize: Use a good quality moisturizer to help combat dryness. Look for products that are fragrance-free and designed for sensitive skin. Applying moisturizer regularly can help maintain skin hydration and reduce irritation.

3. Cold Compress: Applying a cold compress to the affected area may help alleviate pain and reduce inflammation. This can provide temporary relief from discomfort.

4. Over-the-Counter Treatments: Consider using over-the-counter antihistamines if you suspect an allergic reaction. Topical corticosteroids may also help reduce inflammation and itching. However, it is advisable to consult with a healthcare professional before starting any new treatment.

5. Monitor Symptoms: Keep an eye on your symptoms. If the redness, pain, or rough texture persists or worsens, it is essential to seek medical attention. A healthcare provider can evaluate the area and may perform tests to determine the exact cause of your symptoms.

6. Consult a Dermatologist: If the issue does not resolve or if you have concerns about the reaction to the Q fever test, it would be prudent to consult a dermatologist. They can provide a thorough examination and may recommend specific treatments or tests to identify any underlying conditions.

In summary, while your symptoms could be related to the Q fever test injection, environmental factors, or a combination of both, it is crucial to monitor your condition and seek professional advice if necessary. Taking proactive steps to protect your skin and manage any potential irritants can help alleviate your symptoms and improve your overall skin health.
