Hi, I have a question regarding my dad’s health. Recently my dad began to work in new construction site and was appointed with other people to carry the materials they needed because they didn’t have the mini cars used for transporting their materials. Ever since then my dad has begun to get a really bad lower back pain and is getting worst as time goes on. We have a doctor’s appointment in 2 weeks however I am worried that something bad might be occurring. What are some ways we can tell if god fortieth my dad has back cancer or even a tumor? He kind of told me about this little lump that has formed on his back and I don’t know what this could be can you please help me identify what could be the problem.i would also like to know if there is some type of medication he could take meanwhile his appointment comes.
