i got this bag for foot issues [SEP] i do suffer from some foot issues and use heat shiatsu massage on my feet for circulation issues but these salts are for relieving pain when dissolved in very warm water in my foot bath massager okay news flash i am a senior and not as active as i used to be but i am also very aware of keeping good circulation in my feet and making them feel as good as possible arthritis in several joints means if i can lessen pain anywhere i will do that and my feet are important i can truly say that these magnesium salts really do make my feet feel so much better when dissolved in the foot bath water because of my knees i do not take baths any longer but if i could easily sit down and get back up in the bath tub i would definitely try these salts in a nice long soak in the tub i can imagine my whole body feeling as good as my feet afterwards considering the amount i use in my footbath this is not a bad price at all either when i use up this bag i will be buying it again
