Compression leggings

So I was prescribed compression leggings to help with my POTS by my cardiologist. I have 3 different pairs and just started wearing them today. It feels like I've got a giant gently holding my bottom half and it's such a weird feeling. I've never been one to wear tight fitting bottoms so this sensation is strange and uncomfortable to me. Will it feel normal after a while? Is it like wearing glasses for the first time where there's that adjustment period or will I always feel like I'm being gently squeezed? I really want this to work out because I'm tired of fainting several times a day. Any advice or commiserating welcomed
