Go back. Get your GP to double check and compare both ears.
A similar thing happened to me not long ago and I spent weeks feeling horrible with a blocked ear. I thought my GP would say it was wax only he said no. In my case I had also been struggling with bad hayfever and he said it was to do with that. Which I think maybe it was initially. I went back again as it was still annoying me and he gave me something stronger but still it didn't get better and still he said there was no wax. It got so bad that I felt almost numb on one side of my face and had some swelling. I ended up going to hospital that day. By that time I did actually have some wax which was lining the ear drum so it wasnt obvious and had to use that wax softener ear drop stuff and my GP syringed it 5 days later.
