Hi,
Noted your history about having pain under the right rib case that does on to back, is intermittent, has similar pains 3 months ago.
The commonest causes I can think about are as follows:
Nerve pinching at the back with
referred pain to the area under right
rib cage.
Herpes neuropathy.
Costochondritis.
This can be diagnosed by the following ways:
Consult a Doctor for a proper clinical evaluation, examination so that a proper cause can be defined. This will help to get proper investigations done which in turn helps proper management.
You will looked for local tenderness, tenderness at the back in thoracic area.
MRI of spine at thoracic level if needed should be done.
Take an anti-inflammatory medicine like
Ibuprofen if it suits you.
Hot water fomentation.
Local Rubefacient liniment.
Rest also helps in avoiding instigation in any form.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
