Sometimes I have intense tingling and numbness in my hands, feet and forehead along with increased pulse rate. Sometimes the numbness is only on one side (right side).  My doctor checked me and said it's probably because of low pressure. I have been getting these intense tingling feeling for a few days every year since August 2020. It doesn't feel good and I feel very sick when this happens. Please advice what can I do about this and what kind of treatment I need to seek.
