I am just dealing with the same issue with my mother. If the M spikes are low, the best you can do is monitor the condition- three or six month checkups to make sure your protein levels and your antiglobulins (the igg's and others) are not being elevated. Hopefully they will not go up and you will have to be checked on a regular basis for the rest of your life- it's a nuisance, but better than being diagnosed with MM. I wish you the best of luck and health.
