Since you have recurrent pain despite bed rest for 8 weeks, it appears that the compression of the nerve(s) in your spinal canal is severe. Numbness in the feet also points to this conclusion. Under the circumstances, especially if the pain is interfering with your daily activities, surgery to relieve the nerves may be the only answer. The operation usually consists of removing the offending disc tissue and ensuring that no further material from that disc emerges to cause recurrent compression. The surgery, properly performed, has an excellent chance of success. The patient is usually made to stand and walk within a day or two of the operation. In most instances, the patient can resume work within 3 - 6 weeks provided the occupation does not involve lifting weights, bending or squatting. The cost depends on the hospital where you choose to get the operation done and the kind of luxury you demand.
