@GorgyS - next time you see your GP, ask for a blood test including Vit B6 levels - and if you are continuing with B6 supplements (or magnesium or other supplements mentioned in the info from @tri & my post - have them checked every time you have blood tests, to be sure, to be sure.
I believe the tingling & numbness are consistent symptoms of neuropathy .... so it is well worth being aware of this.
As with any medication - different people react differently .... so it is important to monitor your levels of ALL Vitamins & particularly other 'over the counter' meds. Some are actually counter productive to some BC treatments - so always check with your medical team if there are any 'contraindications/problems' with anything that is not prescribed. Even taking Fish Oil capsules can affect your blood thinning ... so if you are put ON TO blood thinners, you are usually asked to NOT take Fish Oil Capsules as well!
take care
