Suggest Treatment For Recurring Right-side Back Pain Triggered By Running, Exercise, Or Heavy Lifting, Sometimes With Nausea, Headache, And Breathlessness

Hi, I am an 18 year old student. I believe I have a kidney problem but I don t know how to solve it. Two years ago, while playing football (soccer), I started to feel pain in my right side of the back of the abdomen (where my right kidney is). At first, I ignored it thinking it had to be something related to muscles but this kept on repeating more and more often and everytime the pain lasted longer. The pain didn t spread to other areas of the body. Also, it can also be triggered by running, aerobic exercises and lifting heavy things. The pain can last from 10 minutes to 1 hour, depending on when I stop that activity and if I stay still while it lasts. I noticed that it lasts longer the more I move. Alongside the pain, before the pain starts, I feel like I am going to throw up and sometimes I even do. Sometimes I even have a headache and I am usually breathless by the end of the activity and when the pain starts. I have gone to many doctors in my country but none could help me. One of them said that I have kidney stones (very tiny) and gave me medicine to solve the problem but it wouldn t. The last time this happened was a week ago when I made only two 70 meter sprints during a football game. I hope someone on the internet can help me. I thank you beforehand
