Despite the injury, Venus came from a set down to beat Clijsters in Thursday's semi-final and afterwards vowed to play in the final against her sister Serena on Saturday.
"I've had treatment with my trainer at home and I'm feeling better," Venus said on Friday. "I didn't practise today as I'm trying to get as much rest as possible for tomorrow's final."
The 2000 and 2001 champion lost her title to Serena in the final last year and she will be gunning for revenge when play starts on Centre Court at 1400.
"It would be a very special feeling to hold that trophy again because Wimbledon is very dear to me," said the world number four. "It's a special place."
"It's where I won my first Grand Slam and I admire the history and the tradition of the championships."
The siblings have so far contested five grand slam finals and although Venus won their first showdown at the U.S. Open in 2001, she has been upstaged by Serena in the last four.
"She's definitely a tough opponent and she's playing very well," said Venus, who became the first women to lose four consecutive Grand Slam finals following her defeat by Serena at the Australian Open in January.
"But it doesn't matter who is on the other side of the net, I'm still going to go for it.
"I would love to win here again. I've had a good tournament, fought through some tough situations and played well in general."
