Lamictal and mg tab

This is a nightmare. I have been on Lamictal 200 mg, tab in morning, for approx. 5 months. About 3 1/2 months ago I started getting muscles aches and weakness, muscle overuse problems, fluid retention ( like 12 pounds), stayed in a trance with very little short term memory. Thought it was everything but this medicine....I am an avid athelite, yes, even at 51. So, I blamed myself for not slowing down. Quick exercising totally, for 2 months, iced 3 times a day on leg muscles. Finally after making it to the summer without a mental breakdown, I went to the emergency room and a new internist to get checked out. Blood work, thyroid, hormones,ok.... Really don't care what they think , I can not walk, it hurts like hell. The Dr. did tell me to get off Lamictal....ok 7th day and I have some relief but it is not complete. Called manufactures, interesting, yes- these are side effects!!! But the studies are limited. Listen , unless you have seizures, get off this medicine... you read the full disclosure of side effects and then search yourself......It can ba a huge FOOOOOPA.....And you are the fool that will end up holdling the bag, not the manufacturer. Hopefully I will get better. Right now , I just trying to stay calm.
