I'm 48 and have been dealing with asthma for about 4 years. I've been taking Telekast L once a day and Deriphyllin twice a day for it. I don't have any issues with blood pressure or diabetes. But lately, I've noticed something strange. For the past two days, just after I fall asleep, I wake up suddenly like I'm gasping for air. It feels like my breath stops, and I get this weird sensation like ants are biting all over my body. I'm really worried about what could be causing this. Could you give me an idea of what might be happening, what kind of treatment I should look into, and if there are any medical tests I should consider? May God bless you.
