health insurance?

i do not have any health insurance and rarely do i feel the pain of that.I have a yearly visit and usually pay cash and it is okay. Lately i have had a specified problem and need to see a specialist. Is it okay or normal to get health insurance temporaily until the problem is resolved and then cancel? Also can you get into trouble for doing that? i don't want to do the wrong thing but these tests and things and meds really add up.

Actually...depending on the state in which you reside, you may be able to get coverage. In some states, "Open Enrollments" cover pre-existing conditions. Please check with your Dept. of Insurance in your state. Ed Harris Broker 28 years
