@heathert I assume you are asking about my allergy shots treatment (allergen immunotherapy), correct? The build-up lasted about 6 months and maintenance the remainder of the 5-year treatment period. During the build-up period, I would receive shots for various allergies every week, then every other week. During the maintenance period, I would receive the same number of shots at a longer interval. I think it was once a month. I'm no longer receiving these shots. That ended a number of year ago.
