SCH && Traveling

So I posted a week ago about a subchronic hematoma and I completely forgot we have a trip for May 9th we have had the tickets since January. My next appointment isn't until May 1 so it's cutting it short if it gets worse or doesn't I am just concerned if the pressure of the flight will affect it. The flight is 4 hours to Mexico I'll be traveling with my husband and 3 year old. So did anyone have restrictions to fly due to sch??
