I completed the 4 cycles of chemotherapy and 33 radiation treatments for my limited Small Cell Ca of left lung . Completed treatment 9/26/23. When do the side effects of treatment resolve??? My peripheral neuropathy is 10x worse than prior to treatment. Certain food smells nauseate me. My legs are weak,my balance is terrible. What can I do to help relieve these side effect??? It seems. the treatment is just as bad as the disease!
