Allergic to Metformin

Did anyone have Side effect while using Metformin.i had terrible hives and my doctor said to stop it completely.i was very much anxious to try this drug,i read it helps with patients who are diabetic and have pcos. Now Doctor had told me to try once more to confirm if i am allergic to it.
Anyone had this problem..? what can i expect my doc will prescribe next,when i researched,the single most effective drug was this.i really hope my skin dont break out again.

 

oleenam,
my dosage is also 500mg/day i was supposed to increase it the next week but by that time it affected me,plus i had some strange feeling in my throat,like as if its closed or something

 

yes i was taking it with food.i am like 99% sure but i really wish i am and doc is completely wrong.i am supposed to try it once more to check if its really the drug causing it. i am aware of the side effects,i had mild diarrhea ,but this not a side effect this is probably drug allergy.

quoted from a website
"Get emergency medical help if you have any of these signs of an allergic reaction to metformin: hives; difficult breathing; swelling of your face, lips, tongue, or throat."

it is something that's been reported and i never thought i would be a victim
My hives vanished automatically when i stopped taking it when my doc told me to.It was pretty bad,it erupted at one place in the begining and as days went by new hives bulged out at new places,i was feeling terrible.

i searched all over internet what could doc prescribe instead of this but couldnt find anything.i dont know :bonk i am just waiting.

 

Is Gycoment prescribed for a pcos & a diabetic..?
