Milk Sensitive Person Looking For An OK Whey?!

[matthewmmcc]

hey all,
so been on whey concentrate for a few weeks and have become totally congested because of it, phlegm in throat, blocked nose ect! Pretty sure im casein intolerant, is whey isolate or whey hydroisolate ok for milk sensitive people?
Note, im aware they're fine for lactose intolerant people however im fine with lactose! and on the subject of this, does anyone know if micellar casein would still give me trouble?
Any help is appreciated, so sick of this vegan s$%t!

Yes you can go with isolate if concentrate gives you issues.
