I am still measuring my oxygen 30 times a day due to fear.  I keep finger in oximeter for minimum 4 min. It fluctuate around 96-98 in index finger and 97-98 in middle finger of right hand in sitting position. 1 . Should I still measure my oxygen like this?? 2. Some days back, index finger reading used to come 97-98...but now it is 96-97 mostly I am really scared if my oxygen is dipping again. I dnt have another symptoms liek fever or breathlessness. My 6min walk test is 97-98 in middle finegr. Please suggest( please suggest if u want to answer this but not suggesting consultation) I shall be highly thankful
