I have had tongue cancer 4 years ago had laser surgery and neck dissection then had radiotherapy and chemo

then 3 weeks ago had laser surgery to remove another Tumor on tongue just above the last one this time when they did the laser surgery I had to have it stitched talking is ok not the same and the side of tongue is numb, but I’m having abit of pain when talking and burning sensation on side of tongue and tip of tongue I’m just wondering if anyone had experienced this and will it go away I know I’m only 3 weeks since I had surgery but it’s quite uncomfortable just hoping it will go away,
