I had back surgery 7 months ago spine fuison. I was playing with my daughter and fell, hitting my knee and back. I have pain. What should I do?

If symptoms. Are very concerning to you get checked out now. If not, consider taking some pain medication such as Ibuprofen (assuming there is no contraindication to taking this) for a few days and see if you feel better. Rest and periodic icing of painful areas can help too. It really comes down to how bad you feel as ultimately nobody can answer the need to see a doctor but you.
