Thankyou for responding.I just had some blood work done through my neurologist which showed high glucose,low carbondioxide in blood and slightly high TSH.I am going back to the endricinologist.He ordered some more bloodwork before I meet with him.I do have so many symptoms.I just don't know what this is.I asked my neurologist if it could be ALS and he told me no.All my symptoms came on days adter that iron infusion.Maybe it is just a coincidence,but maybe not.I thought there was a possibility covid was involved too,but I tested negative for long covid.Right before I had my reaction and before my symptoms came on I was walking on the biketrail in the heat and sun the day before and the day of my reaction it was hot.The sun and heat must have aggravated or brought on whatever I have full force.
