Hi I have condition where I get tight chested and heavy breathing when I walk swiftly or climb stairs or any slight quick paced exercise.
I have had the full angiogram test and was all clear.
I suffer for slight asthma and the consultant suggested I take Nifedipine 30mg per day. This was giving me sever headache, so I reduced to 10mg. This helps when I am walking but does not resolve my tightness of the chest.
Can you suggest an alternative? Or is there any natural way to cure this issue?

Many thanks
Asif
