Laura Robson believes she is finally winning her long-running battle with a chest infection that contributed to her recent early tournament exits.
The British No 2 has been playing with the illness since she claimed Olympic silver with doubles partner Andy Murray at London 2012 and looked below par when she was beaten in the first round in both the Qatar Total Open and Dubai Duty Free Tennis Championships.
Several courses of antibiotics have failed to clear the problem but, having consulted a specialist and been given further medication, the 19-year-old is now on the mend.
"The chest infection is in the process of clearing up. I'll be fine for Indian Wells next month," said Robson.
"I've had another course of antibiotics - stronger stuff - and I'm as good as new.
"It's always tough playing when you're a bit ill, but it was my decision to play in Doha and Dubai.
"I'm still happy that I played, but it's been good to get back on the training court in the last few days."
Robson reached the fourth round of the US Open in September and the third round of the Australian Open last month and is determined to build on her success this year.
"It's very easy to play in grand slams when you have nothing to lose," Robson said. "I played on some of the biggest courts in the world, which is always exciting for me. But some more consistency would be great.
"I want to be seeded at a grand slam this year, hopefully Wimbledon. That would make my life a lot easier and I'll keep working hard to make it happen.
"Things didn't go so well in the Middle East, but generally I'm feeling pretty good about the way things are going at the moment.
"I seem to play well in the US hard courts, so hopefully the next few tournaments will go well."
