Hi I m 21 weight about 11 stone and am 5 11. I only suffer from asthma and migraines. Ok so I ve just gone to bed and before sleeping I ve ate a banana in bed. I ve suddenly got sharp chest pains and pains in my stomach. It feels like wind but it s really painful and makes breathing hurt. It s nothing new as I remember having the same thing before when eating a banana. What could it be? I m not aware of being allergic to anything.
