For nearly one year I have been experiencing pain in both armpits, right elbow area and groin area. There is no swelling in my lymph nodes. Just pain.

Musculoskeletal pain. There are no common conditions that cause pain in these areas. If you do not have fever, weight loss, bowel disturbance or breathing issues the problem is likely benign, not life threatening. Soreness in these areas may be due to muscle pain related to your job or activities. A trial of Tylenol or ibuprofen and a consult with a physician is reasonable. .
