She is feeling dizziness when walking. Last week she got blackouts also. She is also having tingling sensation in fingers and has developed spots on eyelids. We recently got to know that her sugar level is high and bp was high and low both at the same time. Is it due to b12 or due to sugar level? If b12, could you suggest supplements. One ppint i would like to mention she got her first covid vaccine on April 28 after that she got fever. Doctor prescribed her Azithromycin, ivermectin, paracetamol, and Stemetil. Is it all happening due to that? Please suggest.
