The Englishman leads the SPL goalscoring charts with 24 goals this season and is among the nominees for the PFA Scotland Player of the Year award.
But Higdon, who started his career with Crewe, has yet to agree a new deal at Motherwell beyond the summer and would be willing to listen to offers from English clubs.
Asked about his future plans, he said: "I don't know, I just like playing football and that's what I'm doing at the moment. I could go down south and not play, so we'll just see what happens."
Higdon broke Willie Pettigrew's 37-year-old scoring record for Well with a brace against Dundee United last Friday, and he believes the keys to his success this season have been "confidence, playing in a good team and having a manager who believes in me.
"All those ingredients make you want to play football. This has been the best season of my career. My goals-to-games ratio is better than one in two, so you can't complain with that.
"That's what I've been striving for, a season like this. I want another like this next year.
"As the season was progressing I was getting closer to the record then got two on Friday to surpass it and I'm delighted to do it, because it's been there for 30 years or so.
"Hopefully I can get a few more over the remainder of the season and stretch it out a bit more."
