Post surgery query

[Domino95]

Wonder can someone help. I had my first endo surgery on 22nd Nov, I had some complications such as fluid on my lungs, my body absorbed far too much of the gas so had a 5 day stay in hospital. I wasn't moving too much for first the 3 days. They gave me morphine tablets for 3 days straight & IV antibiotics & took home Amoclav which I'm still on. Since the 26th, I've been getting a really weighted sensation in my legs and head, head feels hazy. It hasn't really improved and the left leg has started to get strained & weak now the whole way up the back of it to my butt cheek. Not looking for healthcare advice, but wondering has someone experienced anything similar after surgery & did it just pass with time? I tried to contact my GP today but got no call back. Just want to see if I'm panicking for nothing. Thank you
