i was diagnosised with arthritis when i was 15 and that was due to perthes disease which was diagnoisied when i was 3. i am 19 and since last year i have really struggled with my hip and knee.
i was just thinking that maybe it's not yr knees
most pain is refered pain
when i first had problems it was my lower legs and knees luckly they x rayed my hips and wala i was diagnosised
also it could just be a weakened muscle where physio would be helpful
i currently can't take no painkillers and have tryed everything the best thing is heat it has really helped me and now undergoing steroid injections into my hip joint
one more thing painkillers are good if going sleep because you rest your knees but do not take painkillers while running or anything strenuous.(you always need to be aware of your limits) don't rely on them because your can make your problem worse.( i no what your thinking how can you say that. but i've had 17 years of wincing and sleepless nights but you don't want to make it worse) and swimming and light exercise is great because it keeps the joint mobile as u no stiffness in joints can just be worse
anyway if you strongly believe you have this. then question your doctors i find because we are young we can sometimes not be taken as serious as other people but get this cheaked out and find a physiotheropist
but im no doctor this is just what i've found helps me
