I am on a dosage of 50,000 IU CA PLIVA, after taking the dosage once weekly for one month every Monday I had taken my dosage and ended throwing up very badly for about 10 minutes, after that happened I ended up with a soar stomach, very queezy from my stomach, the next day I had a light breakfast cause I was still feeling bad from my stomach. Ate steamed catfish with veggies did not throw it up but ended up with hives instead all over my body excluding my face. That lasted for four days of and on the flare-ups. I took it upon myself not to take the dosage of that next Monday til now the hives have not occured again but my doctor has done blood work and urine testings but says for me to take the next dosage even though I still don t have the results back. My question is could it be the vitamin D that caused this cause I have concerns of taking the vitamin D again. Thank you for your time .
