Singer Sam Smith has headed over to the US where he will receive specialist treatment on his vocal chords after cancelling another slew of dates on his current tour.

The 22-year-old jetted into Los Angeles on 4 May ahead of his doctor's visit regarding the haemorrhage on his vocal chords.

After touching down at LAX airport, Smith appeared to be in good spirits despite admitting his upset at having to axe upcoming shows in Japan and Manila, Philippines, on 7 and 8 May respectively.

In a statement released via Instagram, the Lay Me Down singer told fans he is "very upset about Japan and Manilla dates [sic]," adding that the situation is "f*****g horrid".

"Very upset about Japan and Manilla dates. I've just left Australia and I'm on my way to the states to see a specialist to see what to do from there... This is f*****g horrid," he said.

A few days prior, the BRIT-winner revealed that he had not used his voice in three days after being signed off work, but was "insanely relaxed".

He wrote in an Instagram post: "So amazing to have this time to turn off, but it does make me realise how much I love what I do, and how much I miss you all when I'm not on stage."

At the end of April, the Stay With Me hitmaker cancelled a number of shows in Australia due to his "bleeding" vocal chords, which he said were "exhausted" after many months of performing.

In addition to his Australian tour, the chart-topper had also cancelled his appearance at the TV Week Logie Awards.

Smith is scheduled to perform at the Hangout Festival in Alabama on 15 May and at Rock In Rio in Las Vegas the following day, however, the fate of his appearance at these shows could be dependent on his doctor's advice.

Many have noted similarities in Smith's vocal injury to that of Grammy-winner Adele, who was forced to prematurely axe her live shows in 2011 due to the same ailment.
