Itchy rash on feet and hands? Anyone ?

Jacky
I'm 31 weeks and I haven't not had any pregnancy symptoms this far...
Until recently started getting a bunch of bumps on my feet, toes, bottom of feet.. 
Also my hands, knuckles, wrists .. 
At my last check up 3 days ago I showed my doctor and she recommended cortisone, but showed little to no concern. 
Googling my symptoms makes me more worried lol 
I'm trying to think positive and say to myself it's just due to maybe the swelling ? 
Anyone go through this ?
