<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I woke up a few days ago with a sharp pain in the middle to right of my chest, under the right rib cage. Since then its been hard to take a full breath, cough and yawn. When i m lieing down i can feel a small lump just right of centre 1cm which is tender, and the tenderness continues to the right under the rib cage. I m 30years old and have been living in Pattaya thailand for several years which has resulted in alot of drinking. I also remember getting a tight chest a couple of years back and when i stretch i expereinced a popping sensation across my rib cage would come and go. The conclusion i have come to is that maybe i have had an enlarged liver due to drinking for quite sometime but haven t notice and carried on drinking, resulting in some sort of liver damage. Since having this pain 4 days ago, i have stopped drinking and gradually it feels like it getting slighty better. However i still cannot take a good breath and still its painful to touch, and this doesn t explain the lump in the centre of the chest. Any ideas? Thanks  <response>: Respected user, HiT hanks for using Chat Doctor.come have evaluated your query thoroughly. This lump requires physical examination, but till this narration seems likely soft tissue lesion with deep neuronal involvement giving agony of pain. Recommended getting primarily ultrasound examination, x-ray chest and further need of MRI has to be decided by the clinician. Hope this will help you. Always welcome for any future doubts. Regards.
