<s>[INST] Hi, I am Neichuvoto Kiso from Dimapur, Nagaland ; India and am 41 years old. I have an inflamation type/numbness on the right side of my chest just below the ribs, this sometimes led to back pain. I have visited the doctor recently and he advised for endoscopy which was done and found that there is an ulcer in my stomach (entry part) for this he has prescribed medicine (Pylokit and Rekool) for 1 and half month. Can I know what is my actual sickness and what should be the best medicine for its treatment. It has already been 5 days but still that feeling of inflamation/numbness is there. Or is it that i go for further treatment. If so which hospital/doctor will be the best as per my place or Neighbouring states. Kindly advice. [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Stomach ulcer can not cause right sided chest pain and numbness. By your history and description, possibility of Costco Chat Doctor. So avoid movements causing pain. Avoid heavyweight lifting and strenuous exercise. Apply warm water pad on affected areas. Take simple painkiller like paracetamol or ibuprofen. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
