I'm a 16 year old femal that is worried about my health 24/7. For the past month my left upper thigh has felt odd. Of source having anxiety heightened my symptoms and now my thigh is the only thing I focus on.. it feels swollen toward the outer side but there is absolutely no visible signs of swelling. I keep on jumping to the worst possible conclusion and thinkinh I have bone cancer. Please tell me what to do/what to think. My brain is taking the best of me right now. Could anxiety cause perceived swelling? Are these symptoms just made up in my head?? Could it be sciatica since I do suffer from left but cheek pain too?
