Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
You got pain on left side since few weeks. worst in the morning, hard to bend down, and to get up from sitting position.
About five months ago you had a
kidney infection.
As you think it is not the kidney infection, and in that you dont find difficulty of movements, and will have a change in urine like frequency, urgency, and burning.
It appears to be the inflamation of the bones and joints.
You need to have neurotropic injections, anti inflamatories etc.
I advise you to consult an orthopedic surgeon for diagnosis and treatment. you may need to have
MRI,besides other routine tests for confirmation.
Avoid taking more of potato, other tubers, tomato, egg, chicken, and sea foods.
Wishing for a quick and complete recovery.
Best regards.
