My male friend 65 yrs old) has been in Alaska a few months and is a photographer living in a tent. He stated he has been bitten by misquitoes and now is having trouble sleeping, having night sweats, racing heart, fatigue, has lost weight due to being sick. He has seen doctors in Alaska and I told him to check with CDC to verify they don t have Lyme Disease in this state and there has been 65 cases so far. They can t seem to pin point the problem, he has sweats, insomnia, high and low blood pressure, EKG and echocardiogram were positive. Heart is very strong, no evidence of any heart disease or malfunction.
