<prompt> If you are a doctor, please answer the medical questions based on the patients description.I fractured my back over 15 years ago when I was 16 in a serious car accident. I am 32 and I have been an avid runner always kept my core strong exercised regularly. However, I have recently experienced back problems such as very tight low back after I run outside for 5 miles this weekend, plus I had a memory foam bed that didnt support me caused my back irritation. I recently went to an orthopedic surgeon who looked at xrays said hardware is fine not to take it out. How do I know if I am experiencing arthritis? Is this pain discomfort going to be common when I do different exercises? I love to hike long distances with my backpack weighing 40lbs, I love to run. Am I going to have to give this up? Is there anything I can do to strengthen my back?  <response>: Hi, Welcome to Chat Doctor. After going through your query I think you are suffering from chronic backache. Treatment of back pain is exercises, NURSING GOLD ONCE DAILY and analgesics diclofenac 100mgSR. Sometimes vitamin D deficiency is the cause so get your vitamin D checked. If it is low then vitamin D supplementation On DK 60K weekly with milk can be taken. Avoid long continuous standing. Sit in a straight posture. Eat milk, fruits and green leafy vegetables daily. To further investigate MRI of the region is advised. I think your query answered. Welcome to any follow-up query.
