<s>[INST] Hi,I took a hard fall on my hip/lower back while mountain biking two weeks ago. About a week later I got really lightheaded. This was followed by nausea while eating, and constipation. The pain on the impact area has since subsided. I think I may have a herniated disc.Do the two things (fall & symptoms) have anything to do with each other?Thanks [/INST] Hello, The herniated disc does lead to compression on nerves due to which there can be pain in their supply area like pain in legs or pain in hand. After such fall if you are feeling continuous lightheaded, nausea or headache then you should consult to your doctor to rule out head injury. Your doctor may advise you a ct scan for this. On lighter side symptoms can be due to goal formation or gas in colon. For which you may have dimethicone preparation for three times a day. Hope I have answered your query. Let me know if I can assist you further. Take care  </s>
