Hello and welcome to HCM,
A history of
frequent urination along with lower
back pain suggests a possibility
urinary tract infection.
I would suggest you to get a urine examination -routine and microscopic examination.
If urinary tract infection is present, urine microscopy will show up.
Enlarged lymph nodes in the groin can be due to urinary tract infection, sexually transmitted diseases or infection or inflammation in the lower limb.
An aspiration cytology of the lesion is suggested.
In this investigation, the cells are aspirated from the lymph node.
This investigation will determine the type of lesion in the lymph node.
A lump between hip bone and rib cage can be due to some organ enlargement,
soft tissue lesion or bony lesion.
An
ultrasound of the abdomen should be performed to look for the site and origin of the lesion.
I would consult you to consult your primary healthcare provider.
Thanks and take care
Dr Shailja P Wahal
