Hi i suffer from anxiety and have been smoking for 19 years...quite heavily,trying to quit now,however i've had clubbed fingers,i think for a long time but not to sure,my doctor noticed them some months ago...but was certain she noticed them before and wasn't overly concerned,but the more i read about clubbed fingers and lung cancer the more worried i get,i'm afraid it's too late...what do i do,also remembering back i had problems in my mid twenties with ibs,and i'm sure the doctor mentioned then about my fingers!!!
