Ian Woosnam failed to win a place in the Open Golf championship during qualifying at Sunningdale on this week – but just to be playing again was a relief.
Last year's Ryder Cup captain returned to action for the first time since mid-May because of post-viral fatigue syndrome/Myalgic Encephalomyelitis.
The 49-year-old Welshman had rounds of 69 and 71 for a level par total but was pleased just to be back competing.
"I got tired the last nine. I just collapsed, but I got round," he told BBC Sport.
"My feet are aching, my legs are aching. I'm knackered. But at the Masters I could only walk about 150 yards because I was in spasm.
"I've mostly been playing in a buggy the last couple of months. I'm only 60-70%, but at least I know what it is in. I got a virus in Asia and it took me over the top.
"I've basically got to rest. I've bashed my body for 30 years and I've just got to eat properly, not drink too much – very difficult!
"People have taken 10 to 15 years to get over this, but hopefully I can play every week now."
Woosnam, who has also entered for the European Open and Scottish Open that follow in July, is down to 614th in the world having failed to earn a single penny so far this season.
