What Do Welts With Purple Rings Indicate?
The welts currently seem to be in a healing stage.
Detailed Answer:
Thanks for asking on HealthcareMagic.
I have gone through your query and understand your concerns. What is not apparent from your query is whether you could have got some sort of insect bite or trauma which could have caused the welts. Anyway, from the description it is evident that they are presently in a healing stage as indicated by the redness converting to purple and the welts becoming smaller.
As of now, I would suggest you to apply some emollients like aloe vera lotion or calamine lotion topically. If there is associated itchiness, you can take cetirizine tablet once a day for a few days. Unless the welts worsen, you need not worry. Be patient and they should be completely gone in 5-7 days.
Let me know if you have any specific queries and I would be glad to help.
