Need advice. Bothers me in daily life.

Hello Doctor, PFA on my query. Sorry for the attachment. I have advised to take chest xray and abdomen scan by General physician. Results came as normal. But still my left and right chest ribs are paining which is mild and uncomfortable feeling for me. Doctor said because of stress I am having pain. I have couple of doubts wanted to clarify. 1. Should I need to test for cancer. I don't have cough. Nor I drink or smoke. But I have itching in my anal. 2. I have attached a snap of my leg which seems to be soriyasis not sure please confirm. It is only in the leg. It is not itching. 3. I have under gone endoscopy and doctor confirmed I have acidity. But taking medications it is not working. 4. Is ribs paininng to left and right is there for more than 5 months. Is that pain will cause because of anxiety and depression. I do yoga and walking. Please advise what should I do further because it bothers me in daily life.
