This is Dr. D.J., experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
Sometimes kidney stones can present like back pain and cause nausea.
So if there is no muscle strain, this should be considered.
Kidney ultrasound an urine tests should be considered.
Urine test will rule out any associated infection.
In mot cases, this can still be muscle strain without any apparent injury.
However, I will suggest a consultation with your GP to rule out the kidney stone possibility.
Usually the pain is located just below the angle of your ribcage on the back
do mean at the chest level?
Any cough or shortness of breath?
then this is something else.
You may have pneumonia or lung infection.
Also asthma can cause these symptoms.
I will suggest you to see your GP for clinical evaluation.
