<s>[INST] Have had lower back pain, off and on for years. I am 47 years old and recently (in about the last three months it changed, some times worse as I sleep, some times wakes me up, before rest always made it better. I am a electrician-maintenance man, 9-5 Mon -Fri and am generally rested on Sat and Sun. Mon -Fri I wake up early and walk on a treadmill, and stretch, this does help. I do not know if connected but my left testicle has experienced some discomfort during this time, no swelling or bleeding, and not all-the-time. Testicle thing seems about gone. Ed [/INST] Hello and welcome to ‘Ask A Doctor’ service.  I have reviewed your query and here is my advice. Chronic lower back pain is a case where the degree of chronicity really matters as mild, moderate, and severe and that differs the decision of treatment. Some cases need endoscopic or surgical treatments. I think in your case you won't need any kind of interventions. Some medications like NSAIDs, acetaminophen, muscle relaxants, some multivitamins and gapapentin is recommended for neuropathic pain. Physiotherapy, yoga, massages are helpful in many cases.  Hope I have answered your query. Let me know if I can assist you further.Regards, Dr. Ahmed Aly Hassan </s>
