Medical collections are keeping my scores low, but I have Multiple Sclerosis and am continually having medical procedures or surgeries. It is impossible to try to keep the payments to the hospitals current. Anyway I was advised to get a credit card and pay it in full every month in order to boost my credit score. Since I don't want multiple inquiries on my credit, can someone suggest a good card with the best features for someone with my FICO score? Thanks!
