Advice regarding achilles injury

Hi, I used to run a good deal about an year and a half ago. Due to overuse, and poor form I ended up getting achilles tendinitis which made me take a break from running. I also developed a swelling on my rigjt achilles tendon, which an MRI diagnosed as a small ganglion cyst(2mm). I have went to 2 physios and some doctors, they all said I shouldnt run if I dont want the cyst to get bigger. I dont want that to happen as I would not like to undergo surgery to remove the cyst.

Has anyone here had experience with a ganglion cyst in the achilles, as a result of running or some injury? Looking for advice on whether I should give up running or not. The physiotherapists mentioned strengthening my calf muscles so it could take pressure off the cyst, but they said i shouldnt run for the forseeable future. Thanks
