Hello, Normally, for the herniated disc lumbalgia you recommend a shorter bed rest period ranging from few days to less than a week. Then you should start physical therapy. You mention that you have been on bed rest for several weeks which is not a good thing as it may increase the risk of complications of other things such as deep vein thrombosis (blood clots in your leg veins). The fact that you say the color of the leg below the knee is blue is a sign of poor blood circulation. I would recommend you to go to ER and doctors should do Doppler ultrasound to rule out the deep vein thrombosis. Then you can go ahead and focus on the herniated disc proper treatment form the neurologist or neurosurgeon. Hope I have answered your query. Let me know if I can assist you further.
