Do people with strong Ur placements tend to have rashes, allergies, or asthma?

rashes - no, sensitivity - yes, but I also have Venus in Capricorn in the 6th with an Aries MC which emphasizes that sensitivity.....fair skin which burns easily and reveals any emotional disturbances I am experiencing. I have a sister with Ur in the 12th and strongly aspected but with Mercury in the 6th - she has allergies and asthma.
