my wife has missed 2 days of work due to foot pain and swelling, it is very painfull for her to walk. it started with the left foot then also the second day went to the right foot, pain has eased in the right foot a little, pain is intense in the top and front half of the feet, i spoke to a pharmacist about different topical pain relievers and she recomended she see her doctor, she made an appointment but its not until thursday. the pharmacist said it could be a heart problem
