Dont panic bro, It happens your legs will pain. It happens with me too.
Just take a cold shower.
Dont think of any thing and have a good sleep.
Massage your legs daily.
And maintain your body eat palak panner or any green vegetable’s sabji, or eat salad. And drink a lot of water.
When I was in 8th i slipped from the stairs and eventually my back was paining and the whole left leg was numb for a week. Then i ate palak panner and maintain a diet with green vegetables and a bunch of fruits. It just took one week to get recovered. Well doctors, told me that it will take upto 3 weeks.
So, maintain a healthy lifestyle and massage your legs.
Hope it helps😊
