Male, 29 years old. Ive had a consistent dull pain in my left lower back (around kidneys) for a couple of months. On a scale of 1 to 10 for pain, its a 1 to 2. I excersize regularly, and drink mostly water all day (no coke, little juice). My urine test at my doctor didnt show any issues.  I occansionally have very mile flutters in the same lower back area. Not sure if I should have additional testing done, or if it could simply be back/muscle pain from an older mattress?
Thank you for sharing your complaint, dear friend your pain seems mostly muscular type but if radiates from back to pelvic area or associated symptoms like burning/difficulty/frequent urination you should keep in mind possibility of renal stone also. Your pain is from at least last 2 months so I think once you should go for sonography of abdomen to rule out other possibilities. If reports are normal no need to worry. For pain you can take analgesic like ibuprofen or for severe pain take muscle relaxant medicine like combination of diclofenac+paracetamol+chlorzoxazon.for muscular back pain exercise and physiotherapy will be much helpful to you.-exercise for low back pain-raise your lower extremity straight from hip joint without bending from knee after sleeping on back and then put down slowly. Same exercise for other lower extremity and then raise both lower extremity simultaneously. Sleep on abdomen and raise your head and chest backward. Do all these exercise daily by increasing every day. Hope this answer will be helpful to you. For more queries please don't hesitate to ask. Get well soon dear friend
