Hi there, thanks for asking. sweating and headaches
could be the signs of withdrawal from the medication you were taking. If you take less than needed of this medication, it could cause sweating, anxiety
, blood pressure change, etc. Your sweating could also be related to your back pain
. If the pain is not controlled completely, the sympathetic system in the body is activated and causes such symptoms like sweating, headaches, etc. These are not dangerous sings fortunately. I wish you the best.
