welcome to hcm,
I really appreciate your concern,
Yes you can have kidney manifestations.
The discomfort or pain if related to the kidneys, may have more intense presentation than you have.
Kidney pain due to stones is very severe. Yes--you may have mild to moderate pain in case of infection involving kidneys.
You need to go for an
ultrasound kidney ureter and bladder; Urine complete analysis and Urine culture and sensitivity to completely rule out the kidney disease involved in this case.
Other causes for this back discomfort may be:-
Muscular spasm.
Constipation.
Indigestion.
For that a thorough physical examination is needed to see if this is a muscular spasm pain (and if there is no associated gastrointestinal symptoms).
For spasm of the back muscles:-
Apply Voltaren gel, massage gently and apply heat pad.
Apply ThermaCare HeatWraps on the back muscles for soothing effects.
Take
Excedrin by mouth for pain.
Avoid bending forward and lifting weights until get better.
Please let me know if you have any further questions.
Thanks. regards.
