6 weeks ago I had a RF treatment because of continous pain over the last year. ( I have discus protheses at L4-L5 and L5-S1 since 5 years.) Today, I still feel a heavy burning pain in my left leg and foot. Since RF , I take Deanxit (2/day), Redomex 25mg (1 x evening) + Contramal Retard 150mg (tramadol HCL) . Then 5 days ago, the dr doubled the Redomex to 50mg because nothing was helping and pain got worse and worse. 2 days ago I had to add Lyrica (75mg, pregabaline) which I took only for 1 day . Against the burning feeling I tried Versatis 5% (lidocaine) for 1 day, without result. Now I just added Voltaren 100 (natrii diclofenacum) .....Anyone has an idea???????
