As per your chart, getting the health insights of your son based on your chart would be an approximation. The birth details of your son would be required for the health related study and analysis.
Your chart indicates some health issues for your child, which could be more or less transitory in nature. The current ongoing time is not quite conducive for you till mid of 2023 and from then onwards you could get a sigh of relief.
Best Wishes.
