Suggest Remedies For Prolonged Swelling And Pain In Leg After An Injury

10 days ago I fell and my knee went down on a parkign curb, busted my pants open. It started swelling I did the RICE, that was on a friday the following wednesday pain was very bad, the whole leg swollen, went to first care they took an x-ray said there was no fractures. It is now Monday and the pain and swelling is still there along with numbess, tingling and redness in the aread under the knee cap.
