Got Botox on my forehead 1st time where 11 shows between forehead. indentation across forehead now after accidental pressure.

On day 1 of Botox, I got tiny insect line bumps on the shot spot. It Wore off by next day. Today on day 10, I Did yoga, placed my head on yoga blocks to rest. Later, I saw a line across my forehead, its indentation that usually would be by placing forehead on some soft edged object that goes away after few minutes. Now after 4 hours this mark hasn't gone! I did warm compression with no pressure. Now, line has moved from center of forehead to the edge now by the temple.
