can mepergan build up in your tissues

Hi, I have been taking mepergan for about two months. I originally was only taking two a day, one every 6 hours, then for the past week i started taking three a day one every 4 hours. I started getting tlittle tingly feelings everywhere. When i take a deep breath and exhale all of my toes tingle. My doctor told me to stop taking them . I have not taken any for 4 days but im still getting the tingley feelings. I tried to take a different type of med,percocet, and when i took it i felt really tingley again . can you help me to find out what is wrong with me.
