Just gonna put this question out there in case anyone has ever had this happen. I have allergies, sinus problems and asthma. Had attack last night and then again today so I went to the Urgent Care today - spent 3 hours - had breathing treatment, steroid shots, etc. Prescribed nebulizer in-home use. Okay, here's the deal, I bought some new liquid vitamins yesterday made by Nature's Plus, Energy Supplements. I have taken the Source Of Life Multi-vitamin one before with no problem. Yesterday, however, I bought the Energy Elixir and the Shot of B12. Both of these attacks came after I took this medicine. How do you know if it is something in the liquid vitamins? Or is it just the pollen, pollen, pollen in the air. Anyone else ever deal with this before?
