Likely muscular: If pain worsens or occurs with changes in position, it is more likely caused by a musculoskeletal source (muscle strain, back issue). Can try antiinflammatory such as Motrin or Aleve (naproxen) with food. However, if pain continues or worsens best to see a doctor to get an exam and possibly some imaging to arrive at a definitive diagnosis.
