Hello
I read your query regarding
sore throat and fever associated with chills and pain over head and entire body. you have one kidney bigger than other and now you have a different pain which arises from back and passes to lower abdomen and to leg of left side.
As you said your fever was associated with chills this indicates towards-
Urinary tract infection, Malaria, and viral fever. Since you have severe pain in body and
abdominal pain radiating to left leg this indicates for fever of infection of
urinary system, no doubt you have associated sore throat.
You are advice for these investigations-
(a) Blood- CBC, ESR, M.P., Ser creatinin, SGPT, SGOT, widal test.
(b) Urine- Routine and microscopic.
(c)
Ultrasonography of abdomen.
After thorough examination and clinical co-relation with signs and investigations one may reach to correct diagnosis and treatment.
Regards.
