The drummer's band Blink-182 was forced to postpone dates in the Las Vegas residency last month when his doctor warned him not to perform due to the heath risks.
Sharing a video on YouTube - which shows his journey from discovering the issue to working his way back to normality - Travis wrote: "It's been the longest 4 weeks without playing drums. I played through two shows in Vegas with infection and blood clots before I was able to get a clear diagnosis from a doctor. Here's an update on my road to recovery."
The clip shows the musician visiting his doctor, and receiving the news that although the clots in his arms won't move to his lungs, drumming will still cause inflammation in his arm.
Travis took to his Twitter last month to reveal he was suffering from blood clots and a staph infection.
He tweeted at the time: "Blood clots in both arms and a staff infection wasn't the news I was hoping for. I'll be back soon, thanks for all the love & prayers (sic)"
