As a follow up to the voice message I just left, I went with your son to his follow up doctor’s appointment. Everything seems like it is back to normal. Your son said he gets tired but less so every day. The doctor encouraged him to continue taking folic acid (Vitamin C ) and said that would pass. The doctor requested a liver function test just for documentation purposes and said that from observation he could see things were okay. The results of the test will be available tomorrow.
Liver function test results are back. Results are good. All values in normal range or improving. Your son also told the doctor the tiredness is improving. Good news.
