I went to Dr. Welman Lim for an injury that had happened on my foot and I was unable to walk properly. I was worried it was Morton’s neuroma or some issue as it had swollen but there was no bruising. In the end he prescribed Korean Salon Pas which he charged for $20 each and said I should buy 2. I followed the doctor’s orders but when I got home, I googled Arex SinsinPas and was shocked to find out that each packet was being sold at $7.50. How can a provider charge more than double for something you can find over the counter?
