Your symptoms are real, and they have a name.
What you're feeling could be a recognized medical condition called hidradenitis suppurativa (HS). It's driven by inflammation under the skin, it affects many people, and it's treatable. Because it tends to show up in private places, it often goes unspoken, so most people live with it for years before they ever hear the word HS. The moment it has a name, you can start getting real relief.

This is currently the best endocrinologist I have seen in the United States. He patiently listened to my questions and provided answers. He also gave very professional opinions and suggestions. Online consultations are very convenient. The doctors are professional, patient and proactive in answering questions.
