Warm sensation in feet

Hi I am a 20 years old female, I had experienced a sudden heat sensation in my left foot for the last two days. The feeling lasts for about 3-5 seconds each time and happened about 5-10 times a day? I did feel numbness in my left foot once yesterday. Oh and I didn’t have my normal periods since I was 16, I went to the doctor and he said it’s normal for me (hormonal imbalance and maybe abit overweight? I am 154cm and 63kg) so I usually only have 2-3 periods a year. But after I take the evening primrose oil in July this year, I have my normal periods back for August and September then my period is abnormal again, that is I haven’t have my period until now (idk if this is related to my hot feet but I am just saying in case you need to know) So what exactly is the problem and do I need to worry about it? Thank you.
