I suffered lead poisoning 5 years back. Treated with chelation therapy with medicine cilamin 250mg. In 2012 suffered mild stroke on left side of body. MRI done on brain and it was ok. NCV test was ok. But Now suffering from allergy, backpain with multiple slipped disc, sciatica on left leg, IBS, numbness in left side of body, weakness in left side brain, short term memory loss. I am not recovering from back pain though Physiotherapy along with exercise has been done many times. Doctors usually only gave medicine like gabapentin and calcium with vitamin d3, but they don't suggest anything. It only gives me temporary relief. Is all above diseases are after affects of lead poisoning. Please give consultation?
