 [ Symptoms ] i have been getting heavy periods tiredness my whole body is tender migraines [ Disease ] i am sorry you are going through this i would not be too quick to self diagnose osteoarthritis your knee pain could be caused by a number of conditions other than arthritis the very fact your sport involves a lot of knee twisting would lead me to suspect injury as a likely culprit for your pain issues i would suggest you have your knee checked out by a medical professional to get a diagnosis once you know for sure what you are dealing with then you can work with your health care provider on a treatment plan that enables you to continue with your sport one thing i want to add is this be careful about taking non steroidal anti inflammatory medications nsaids like aspirin ibuprofen or naproxyn for your pain these medications have blood thinning properties which can increase bleeding and swelling from injuries you sustain in your sport i wish you all the best
