Hello, My husband has a reoccurring lower left back pain. He hurt it in the shower the other day. Its a little different this time as the pain which is very bad has now gone into his left leg and knee as well as his back. He was up all night because he couldn t get comfortable. This has been going on for three days.
Hi I am Chat Doctor. .  In my opinion i don't want you to worry on your husband this is usually due to the inflammation of his past shower injury that may have caused compression on his sciatic nerve roots causing such neuropathic pain.  For now I suggest painkiller like Advil tabs when needed, icing it for the 1st 48 hours, massaging it with topical gels, muscle relaxants will be effective for him. Otherwise, I suggest X-rays and MRI any minor fissures or bone injury for proper evaluation and management.
