You should be more concerned about the growth and its treatment than the pain relieving medication. The root cause of your pain lies in the possible growth. You must first get your growth evaluated and treated after detailed clinical workup. Pain killer medications will be given to you after clinical evaluation, starting with the less powerful ones.
Please talk to your doctor informing them of the intensity of pain you are having and they may give you opiates after consideration. Always take ibuprofen
in recommended doses and after food.
Hope this helps
