There are similar bump-like lesions on the thigh and back of the thigh that resemble acne?
Hello, doctor! Before asking my question, I have done a lot of research.
The day before yesterday, after taking a shower, I noticed that there were painful lumps the size of a 5 to 10 NT dollar coin on the thigh under my buttocks.
I can assure you that these are not acne...
nor are they signs of a sebaceous cyst...
because if they were acne, they wouldn't have appeared so quickly.
Later, I found three more large lumps on my buttocks...
The next day, I noticed 7 to 8 similar lumps on the side of my thigh and above my knee, which have developed over 1 to 2 days.
They are painful to touch and uncomfortable when sitting.
I applied a topical anti-inflammatory ointment, which provided some relief.
I visited a general clinic, and the doctor said they were unsure of the cause...
suggesting it looked like folliculitis but it seemed unlikely to have so many at once.
I have never experienced this before.
The doctor prescribed a similar anti-inflammatory ointment and oral medication for me to try for a day to see if my condition improves before visiting a dermatologist.
Is this situation considered normal? My family says I'm overreacting, but I'm still very worried.

Without actually seeing the lesion, it is impossible to determine the issue.
If it is causing significant distress, please seek medical attention as soon as possible.
A proper examination is necessary to understand the problem and to determine the appropriate treatment.

More Info
It sounds like you are experiencing a concerning issue with painful bumps on your thighs, which can understandably cause anxiety. Based on your description, there are several potential causes for these bumps, and I will outline some possibilities along with recommendations for further action.
Possible Causes
1. Folliculitis: This is an inflammation of the hair follicles, often caused by bacterial or fungal infections. It can present as red, painful bumps that resemble acne. If you have been sweating or wearing tight clothing, this could exacerbate the condition.
2. Cysts: While you mentioned that these do not appear to be cysts, it’s worth noting that sebaceous cysts can develop in various areas of the body, including the thighs. They can become inflamed and painful, especially if they become infected.
3. Hidradenitis Suppurativa: This is a chronic skin condition characterized by lumps under the skin, often in areas where skin rubs together, such as the thighs and buttocks. It can be painful and may require specific treatments.
4. Allergic Reaction: Sometimes, an allergic reaction to a product (like soap, lotion, or laundry detergent) can cause localized bumps and irritation.
5. Insect Bites: Bites from insects can also cause localized swelling and pain. If you have been outdoors, this could be a possibility.
6. Skin Infections: Bacterial infections, such as cellulitis, can cause painful, swollen areas on the skin. This is often accompanied by redness and warmth in the affected area.
Recommendations
1. Observation: Keep track of any changes in the bumps, including size, number, and associated symptoms (like fever or increased pain). If they worsen or new symptoms develop, seek medical attention promptly.
2. Topical Treatments: Since you have already started using an anti-inflammatory ointment, continue to apply it as directed. Over-the-counter hydrocortisone cream may also help reduce inflammation and itching.
3. Avoid Irritation: Wear loose-fitting clothing to minimize friction and irritation on the affected areas. Avoid tight clothing that may exacerbate the condition.
4. Hygiene: Maintain good hygiene by washing the affected areas gently with mild soap and water. Avoid scrubbing the bumps, as this can lead to further irritation.
5. Consult a Dermatologist: If the bumps do not improve with topical treatments or if they continue to multiply, it would be wise to see a dermatologist. They can provide a more accurate diagnosis and may perform a biopsy or culture if necessary.
6. Medication: If your doctor suspects an infection, they may prescribe antibiotics or other medications. Follow their advice closely.
Conclusion
While it can be easy to dismiss skin issues, especially when they are new and painful, it is essential to take them seriously. Your health and comfort are paramount, and seeking a second opinion from a specialist, such as a dermatologist, can provide clarity and appropriate treatment. Remember, it’s always better to err on the side of caution when it comes to health concerns. If you notice any systemic symptoms like fever, chills, or spreading redness, seek medical attention immediately.
