I have been having pain in my right calf for about twenty days now..it does not go away Ican not walk because when I stand up it feels like my veins are filling with blood and they want to explode..ive been to the hospital three times for severe pain and each time its undiagnosed they prescribed norco and its the only thing that helps with pain but pressure is still there and still cannot walk..for the past five days the pain is now inboth calfs and both thighs..I only get up to go to the bathroom and I am in pain the whole time I use crutches to help get to the bathroom and I have to position them against the tub so I can elevate my legs..last hospital visit I had an ultrasound on my legs but they found nothing..I seen my regular dr two days ago and he has no idea..I am now waiting for an appt for a rheumatoidoligist but the pain is so severe now im in tears..I dont even want to go to the bathroom no more because that equals pain..what can it be??
