He does not have pain when he walks but when he seats it hurts. He is courier driver. He is 61 years old . He is pretty fit , he 5 7 ans weights 165 pounds [/INST] Dear-thanks for using our service, I understand your concern about your husband and will try to help you with my advice. His pain could be secondary to tendinitis. His pain is worse when sits because is pressing the area that is inflamed. Due to his job, he needs to be sitting most of the time, that makes the pain worse due to chronic compression. He might try a back support or a back cushion, that might help the pain. If it doesn't get better, he will need a plain X-ray of the area. He can try anti-inflammatories as ibuprofen for pain control. I hope my advice has been helpful Chat Doctor.  </s>
