hii,,,

I was having very less pimples. I consulted doctor and they got reduced.
suddenly after one month very tiny pimple kind of things appeared on my chin in huge amount. day by day they are growing rapidly. whole face except forehead is filled. doctor said that they are acne. but I'm unable to digest this. Just in 3 days my whole face turned with 100s of acne. how is it possible?? I'm scared of going out as people are looking at me strangely. doctor has prescribed Azithral 500 and iiaprazole and doxycycline and lactic acid bacillus capsules and Deriva CMS gel..
will these things work?? plz suggest me some good tips to overcome acne soon.
Thanks.
