[/INST] Hello, As per your history, it may be due to nerve compression. For further assessment you may require MRI back and nerve conduction studies after consultation. Till then, you can take tablet sildenafil one hour before sexual act. Foreplay will help. Along with that avoid stress. Take proper rest and balanced diet. Discuss issues with your partner Hope I have answered your query. Let me know if I can assist you further.   </s>
