This could be due to deep vein thrombosis in lower limbs.
In this there is clot development in veins of limbs.
These clots can also reach lungs and cause chest symptoms.
You need to visit your doctor as soon as possible,
Special test known as color doppler is required to diagnose this.

There is possibilty that your symptoms are due to spread of infection due to injury you suffered.
You should not wait and get immediate medical attention.
Mean while you can take OTC pain killer acetaaminophen if there is pain.
Do not delay.
If infection is there then you need antibiotics.
ok thanku for your for your help will call doctor straight away
Thanks i hope this helped.
