hi, im a 24 years old female(student) and i have been coughing for 3 years or so years now. it first i was told i had bronchitis and then l was later told that i might have asthma. i was given advair , albuterol , prednisone , singulair, claritin and antibiotic( when it first started). but i dont think its really helping. i often cough when i have from one place to another. i guess its the change of smell of the environment. i cough and have tinkly feel in my head when i go to place where there are too many different smell going on. do you think i have smelling allergies? also my bones (the joints) often make a pop/ click noise when i move around especially my pelvic bone. i asked my doctor and she said it might be gas but i think their might be something wrong. because when i run, i feel pain in my leg bone. im not sure if in lacking calcium because i dont really eat food that contain calcium. for the reason i just started taking some multi vit and calcium supplement. what do you think?
