Red Bumps on Arms: Causes and Solutions for Skin Issues

There are small bumps on the arm?

Due to the unclean work environment and the need for welding, combined with the recent hot weather causing me to sweat frequently, I have developed red, pimple-like lesions from my elbow to my palm.
They are painful when pressed, and I am unsure if this is a rash or folliculitis.
It seems to appear every time I sweat, and it does not itch.
I have applied medication, but the condition has not improved.
I am uncertain if the doctor I consulted was unprofessional or simply did not understand, as he even asked me what this was.
I would like to seek your advice on how to improve this condition.

It's not that the physician is unprofessional.
It sounds like folliculitis, but without seeing the actual condition, I cannot be certain.
You should consider that an unclean work environment, combined with hot weather and sweating, may be contributing to your skin issues.
If you don't make an effort to improve these factors causing your skin problems, how can you blame the physician's medication for not helping you?

More Info

When it comes to understanding red bumps on the arms, especially in the context of your work environment and recent weather conditions, there are several potential causes and solutions to consider. Based on your description, it sounds like you may be experiencing a condition that could be related to folliculitis, heat rash, or even a form of dermatitis.

Folliculitis is an inflammation of the hair follicles, which can occur due to various factors including friction, sweat, and bacteria. Given that you mentioned your work environment is not very clean and involves welding, it’s possible that the combination of sweat and exposure to irritants could be contributing to this condition. The fact that the bumps are painful when pressed but not itchy is also characteristic of folliculitis.

Heat rash, or miliaria, is another possibility, especially since you mentioned that it worsens with sweating. This condition occurs when sweat ducts become blocked, leading to small red bumps that can be painful or tender. Heat rash typically resolves on its own once the skin cools down, but it can be uncomfortable in the meantime.

Dermatitis, which includes contact dermatitis or irritant dermatitis, could also be a factor. If your skin is coming into contact with irritants from your work environment, it may react by developing red bumps. This type of dermatitis can occur without itching, especially if the skin is not severely irritated.

Solutions and Recommendations:
1. Hygiene and Skin Care: Ensure that you are maintaining good hygiene. Showering regularly, especially after sweating, can help remove irritants and bacteria from your skin. Use a gentle, fragrance-free cleanser to avoid further irritation.

2. Avoid Tight Clothing: Wear loose-fitting clothing that allows your skin to breathe, especially in hot weather. Tight clothing can trap sweat and exacerbate conditions like folliculitis and heat rash.

3. Topical Treatments: Over-the-counter topical treatments containing benzoyl peroxide or salicylic acid can help with folliculitis. These ingredients can reduce bacteria and help clear blocked follicles. However, if you have already tried topical medications without improvement, it may be time to consult a healthcare professional.

4. Cool Compresses: Applying cool compresses to the affected area can help soothe inflammation and discomfort. This is especially useful if you are experiencing heat rash.

5. Consult a Dermatologist: Since you mentioned that previous consultations have not yielded satisfactory answers, it may be beneficial to seek a second opinion from a dermatologist. A specialist can provide a thorough examination and may perform tests to determine the exact cause of your skin issues. They can also prescribe stronger medications if necessary.

6. Avoid Irritants: If you suspect that your work environment is contributing to your skin issues, consider protective measures such as wearing gloves or long sleeves, and ensure that your workspace is as clean as possible.

7. Monitor Symptoms: Keep track of any changes in your skin condition, including new symptoms or changes in the appearance of the bumps. This information can be valuable for your healthcare provider.

In summary, while there are several potential causes for the red bumps on your arms, understanding the specific nature of your condition is crucial for effective treatment. Maintaining good hygiene, avoiding irritants, and consulting a dermatologist for a professional evaluation are key steps in addressing your skin issues.
