Hi Steve in the UK,
Yes, that will go away when the swelling subsides. Hang in there. That fullness made me want to give up along with other horrible symptoms I suffered and much pain. I assure you, it will pass and if not, you'll need to talk with the doctors. I didn't even take my steriod pill to reduce swelling after CK. I had a bad reaction to steroids and ended in ER all night once.
Regards and welcome,
Palace
