<s>[INST] I have had 2 spine surgeries (L4, L5) Discectomy 1st 15 years ago and the last June 2009. I was told at the last surgery I would have to have a fusion of L4, L5, sacrum. In the last few weeks, my back has been hurting alot along with my right testicle. I asked my Dr about this, and he said the 2 are not related. However, My testicle only hurts whne my back hurts and the Dr cannot give me another reaon for the pain. Is this because of the back pain? Also, if I do have the fusion, how much range of motion will I lose? [/INST] Hello, As per your history, it may be due to nerve compression. For further assessment, I would suggest you to do MRI back, nerve conduction studies after spine surgeon consultation.  For testicular pain you may require Doppler scan. Till then for pain you can take tablet acetaminophen. Apply diclofenac gel. Heating pads will also help. Use scrotum support. Avoid strenuous activity. Hope I have answered your query and let me know if I can assist you further.  </s>
