3 years ago i fell down some stairs and smashed my knee on concrete,i was in agony for weeks couldn't walk or touch it, but was stubborn and battled through,i had just had i baby and have no family for childcare so hospital for myself and my injuries an emergency basis only,as it was healing it did nothing but pop and crunch,i twisted it as i was moving a tv stand my foot stayed still but the knee went and it popped to which i couldn't walk properly for days,i am now in a state where i can hardly crouch and the knee crunches aches and cracks as i walk and i have a golfball sized lump just under the knee,i went to my G.P who stated is was Osgood schlatters,but i have a feeling i have smashed it so i went back for a 2nd opinion to a skeletal specialist to be told to lose weight but standing 5ft9inch and 140lb im not going to listen to that so i went for a 3rd opinion and he has now referred me for an x-ray,i should of gone when i first did the injury i am silly for not doing so but now im scared that at 28 my knees smashed to bits and its all my fault.
