<s>[INST] Hi I am 41 and normally in good health. I don t drink or smoke and keep fit. Today I have had a pain in my right hand side that comes and goes. When I bend over it hurts more and is a struggle to get back up as the pain is quite severe. I m also breathless . It cannot be my appendix as it was removed when I was a teenager. I feel perfectly well otherwise and have no other symptoms. I have eaten as normal today but did notice further discomfort on eating my lunch. [/INST] Hello, Thanks for the query to Chat Doctor. Forum. You mentioned that pain is on the right side, but where ? Is it in abdomen ? You mentioned two things that pain is more after lunch & there is breathlessness. So these two things are related. May be due to pain in the liver, Lower part of right lung, Thickened pleura. Consult a physician and get his opinion. Get in ultrasound of liver and X-ray chest PA view. Take treatment according to situation. Good luck.  </s>
