My husband was diagnosed with L5 S1 but recently experienced persistent severe pain in his hip, thigh, calf and foot. What concerns me most is that he runs an intermittent low grade fever, feels clammy and sweaty, and has been complaining about pain in his side. He woke up last night perspiring profusely saying his chest hurt. I ve never heard of these symptoms with the type of lower back issue he has.
Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should rule out pneumonia in his case. Pneumonia can cause fever, chills, perspiration and chest pain. Pneumonia can also cause systemic symptoms like weakness, lower limb pain, Tiredness etc. So better to consult pulmonologist and get done clinical examination of respiratory system and chest x-ray. He may need antibiotics and other supportive Chat Doctor.  Tell him to
