Having a bad day today. Didn't get up till 2 15pm can't remember exact time we went to bed. What I'm wanting to ask is i wear lidocaine patches for 12hrs on a night. I take a number of other medication. But now my left I knee is swelling like my other knee does. Do u think i can wear 2 lidocaine patches at the same time 1 on each knee. At present i take morphine tablets, pregabaline tablets ammatriptaline ,dulocatine tablets also morphine patches also lidocaine patches. What doo you think?
