I am feeling just like you and I believe you. I have symptoms ( burning, hot, cold sensations) that were gone for 11 years and returned 1 day after the shot - full on within 3 days. I too had Pfizer in February. I still have all my symptoms - nothing has changed. I too did not take the 2nd shot. I have seen two doctors, primary care and oncologist. They both have expressed this could be a coincidence with no relationship to the vaccine. Really? The primary care is suggesting some tests - mostly to see if I have other more horrible things. Again, i believe you and I understand your frustration. Thank goodness for this site where I can hear of others in this predicament. Otherwise, I would have thought I was all alone. Take care.
