Dr wants me to start Pentasa...my insurance won't cover it and I asked for a less expensive medicine...I have called 3 days in a row...today I left message saying I would take Pentasa even though I will have to charge it on my card but really just wanted to ask him a question...am I being unreasonable to think he should have returned my call after 3 days? Also he hasn't even explained why he wants me to take it....only positive test has been a high IgG Pill cam negative, fecal cal neg. ct scan negative. I'm very frustrated!
