I do sometimes bit more numbness. I think l can tolerate the pain just as long as l can get off of it because it really isn't helping. So it's really defeating it's purpose. So that's why he gave me tramadol also.And the tramadol can be addictive. That's the only pain med l can take so l don't want to take that and l can't take any NASID. I am trying to slowly decrease the meds but when l tell the doctors what meds l stopped taking they get a little frustrated with me because they can't keep up when l tell them which one l am not taking.
