<s>[INST] 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 didn't 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? [/INST] Hi, Welcome to healthcare magic. After going through your query I think you are suffering from chronic backache.. Treatment of back pain is exercises, NUROKIND 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 (Bon 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. </s>
