What Causes Pain Under The Left Rib Cage Radiating To The Back?
The most likely is you are developing Herpes Zoster.
Detailed Answer:
Hi welcome to Health care magic,
There are various possibilities.
The most likely is you are developing Herpes Zoster. Pain comes first and rash later.
It is most likely a nerve root pain -commonest cause is Herpes. Look out for a rash--comes after 4th day.
In some people there is no rash too.
Try--- a high dose of B complex, avoid the sun, take Omeprazole 20 twice a day (remote possibility it is acidity), and take Motrin (Ibuprofen) 400 mgs twice a day.
If it is Herpes, the whole process will last 21 days since it is due to Chicken pox virus affecting adults in a single nerve.
If rashes appear, go to your doctor. He may put you on Acyclovir and even steroids if he thinks it is required.
If no Herpes---get an x-ray of neck and back spine done.
It could also be one of your renal stones causing obstruction.
