[...] is my primary dr but Dr Sygaco is the Dr I see as I had blood clots in my leg. He is very knowledgeable and we discussed shingles vaccine/meds as I had shingles and was advised by my rheumatologist years ago not to get the vaccine as I get an infusion every 4 weeks for RA. Dr Sygaco checked to see if there is an interaction with my infusion & there is not so I will discuss with my rheumatologist next time I see him.
