I had been casting and shooting for 20 years.
I asked my doctor to test me for lead. She said no, your insurance will not cover it.
I said "I will pay for it". She said OK, I will put down you were exposed. That was in 2006.
The next day I got a phone call. Lead level was almost 50. I asked what to do. She said
I am finding out, you are my first patient with lead poison.
I got letter and call from the state. I chose not to participate in the program.
I gave up shooting, casting and reloading for a few years.
Levels went down below 20. I have been back to shooting and reloading for a few years.
Levels are now below 20. Last test was a year ago. It was 17 and I got a call from the state of NY.
I don't think the symptoms of OP are from lead poison. If they were, his levels would be still high.
Symptoms I had were aching joints, and my "Pay Attention" was not working well.
I now shoot coated, plated or jacketed bullets.
I believe some folks are more susceptible to it than others.
