A persistent ulcer at the tip of the penis after taking Doxycycline suggests that further evaluation and treatment are needed, as the ulcer may be due to an infection not fully treated or another cause.

🩺 What This Likely Means

The burning sensation improving with Doxycycline indicates some bacterial infection was addressed, but the ulcer remaining could mean a resistant infection, a viral cause (like herpes), or a non-infectious condition. It is important not to self-treat further without a proper diagnosis.

🩺 Recommended Next Steps

• See a urologist or a dermatologist specializing in genital infections for a thorough examination.
• They may perform tests such as swabs or blood tests to identify the exact cause of the ulcer.
• Treatment will depend on the diagnosis and may include antiviral medications if herpes is suspected or other targeted therapies.
• Avoid sexual contact until cleared by the doctor to prevent transmission or worsening.
• Maintain good hygiene and avoid irritants around the area.

⚠️ When to Seek Urgent Care

• If the ulcer worsens, spreads, or is accompanied by fever or severe pain.
• If you notice swelling of the groin lymph nodes or difficulty urinating.
