Hello girls, help me out if you have something like this ?? A week ago…

Hello girls, help me out if you have something like this ?? A week ago, a rash started, bumps on my arms, legs and stomach, for three days I excluded sweets, citrus fruits, all kinds of yogurt etc - it didn't go away. Then the doctor prescribed 1 tab Suprin in a day, I've been taking it for three days, my hands and stomach calmed down, legs are gone altogether. Now the doctor says to try Ursodex capsules 2 caps at night, but she didn't explain why ??‍♀️??‍♀️??‍♀️
