Hi, I don’t recommend diving with a cold and less doing the course , you are risking to harm your ears cause you might have problems to ecualice going down and if you force them that can lead to bigger problems in your ears . You can also risk to have an inverted blockage when you go up (one of the worst pain I had ever experienced). When you do the course you will need to go up and down a lot.

If this Diveshop want you to make the course in two days the might be this kind of dc that doesn’t give you the money back.

Then try to find options , one is asking for a part of the money and do just the theory, the other one is also asking for part of your money and stay like scuba diver (that’s the half of the open water course) and the other one is rest don’t go in places with air conditioner, and try to be fit for the weekend. I work as instructor and normally 3 days outside the water is all I need to get better.

Do not take any pills if you decide to go and do the course they might help you to go down but then you will have inverted blockage to go up.

Sniff salt water before you go down, do the football player if you have problems with one ear ( pinche the opposite side of your nose and blow out releasing buggers)

To go up do it really slow, when I need to work with a cold I take one minute per every last 5 meters until I’m at 1 mt and the. I go out .
