Hello,
Welcome to Healthcaremagic.
Both Puffiness of face and left upper quadrant
abdominal pain may or may not be relates.
because puffiness of face may be seen in allergies and kidney diseases.
Left upper abdominal may be either from heart cause like
Heart attack, angina etc.
Some other causes are Splenic causes ie.
ruptured spleen, splenic abscess.
Kidney causes are
renal infection, stones or chronic or
acute renal failure etc.
Even gastric problem can be a cause.
Since the facial puffiness decreases in one or two days most probably allergy or kidney problem could be the cause.
Please do an ECG and X ray chest to ruleout Heart and lung disease.
We have to do Ultrasound abdomen, blood urea , creatinine, and urinalysis to rule out kidney disease.
As tenderness is in left upper quadrant, apleen may be involved. Check for hemoglobin and other RBC parameters and Peripheral smear for RBC details.
Hope this helps.
Take care.
Regards,
Dr.Manjeth.
