I am 62, 6 2 and healthy. 2 nights ago, I tripped ovr my dog while in the bathroom and fell hitting my lower to side back on the toilet. I get pains in my lower right back like a spasm after I cough, bend over from the waist, or contract that side of my back, or move in bed (I am most comfortable sleeping on my back).
Hello, I read carefully your query and understand your concern. Your symptoms seem to be related to the fall and injury. I suggest using anti-inflammatory medications such as Acetaminophen to relieve the 5. I also suggest using cold compresses for local application. If the symptoms continue, I suggest doing a X-ray to exclude a fracture. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.
