Hello, I am 27 years old male, I went for 22km trekking expedition. Next day while sneezing I felt a sudden pain wave through my left lower back. I took it casually and went to play soccer next day now I'm feeling it for past 3 days although the intensity is low-mild. I had similar back pain with high intensity around3 months back while picking up something from the floor. Went to see a doctor and foot x-rayed he told it's a sprain and have me passion killers it subsided in couple of days. Should I visit again to the doctor or it will cool down in a few days?
