Question: Snow border suffers stiffness in both Achilles…can’t get to a doctor

i have been getting a pain and stiffness in both my Achilles whenever I get up from a rest, for example after sleep or after a meal, a journey sitting down etc, making it difficult to walk, it only lasts around 5-10 mins each time. It started last winter when I worked in a ski resort and snowboarded a few times a week it then stopped for a while then it started again, and most times after a sit down a few months ago, I’m not a runner or anything. Is there anything I should be worried about or anything I can do ? I can’t really get to a doctor at the moment
