22 year old, 5 foot 5 about 10 stone, have asthma bought on by allergies. This weekend been getting back pains/ lung pains- although not linked to any kind of cough and doesnt sound wheezy, my sister a trainy doctor said my lungs sound crackly rather than wheezy- have needed to take my sabutmol more than usual. Also been feeling dizzy, weak, tired and getting headaches (never usually get headaches!) Feels a bit like im not in my body properly- constantly light headed. Have had a weekend of doing nothing particularly stressful, no alcohol, no cigarettes etc.
