The Fir Park favourite bemoaned the decision of referee Willie Collum on 34 minutes after Andy Webster appeared to crash through the back of the forward.
The incident came 20 minutes after Danny Grainger had opened the scoring with a rasping drive from 25 yards.
But Higdon reckoned McCall's men were the victims of a poor call by the ref.
"It's a stonewaller if you ask me," said the 29-year-old. "Webster's come right through the back of me. If it happened outside the box the ref might have given it, but we didn't get much off him.
"Big Suttie (John Sutton) came on for Hearts and got three or four fouls straight away and I had been grafting for 90 minutes and got none."
Despite the end result, it was a positive performance from Motherwell as they returned to action following a three-week absence due to the international break and a power cut two weeks ago against Dundee United.
It was the Steelmen who looked to be the live-wires in the early stages as Jamie Murphy drew a diving save from Jamie Macdonald.
However, Well's defence short-circuited soon after with Fraser Kerr allowing Grainger time to pick his spot and fire the hosts ahead.
Despite a valiant attempt in the second half, with Higdon and Nicky Law going close, a deserved point escaped Motherwell as Hearts moved to joint seventh in the SPL.
Higdon is now looking to the game at Fir Park on Friday against Hibs as an ideal chance to get his team back on track.
"I thought we played well but didn't look like scoring, I also didn't think they looked like scoring, but it wasn't a bad game.
"We have a game on Friday so, hopefully, we can get the right result."
McCall, who watched Shaun Hutchinson go off just before the break with a hamstring strain, said: "We have lost to a terrific goal from their point of view. We are disappointed we didn't close him down as Grainger has a great left foot.
"There's no disgrace to come here and lose because they have good players. Despite not defending well for the goal, I thought we merited a point."
Regarding Hutchinson, the Well boss added: "We're hoping it's only a slight niggle rather than a major tear. But that was a bit of a blow for us to go in 1-0 down and without one of our key players.
"But we're hoping it won't keep him out for too long."
