Thanks for providing more information.
As per your description,your symptoms(pain,warmth,swelling, broken capillaries on right leg)indicate the possibility of Deep vein thrombosis,venous insufficiency.
Other possible cause of radiating pain in leg can be
Nerve compression due to degenerative arthritic changes in lumbosacral spine.
And it may require an urgent medical attention.
So i recommend to visit ER or consult your family doctor ASAP.
Elevate your leg and take OTC Motrin in the meantime.
Hope this helps.
