Hi from a few days, I have this weird feeling in my left leg calf. It feels like some heavy liquid or something weighing inside. There is no pain or swelling and it is only in one calf. The feeling is not all the time (comes and goes on it's own) and no particular pattern in terms of my sitting or standing. Medical History- recovered from mild covid around 2 months back. Have episodes of back head pain from 1 year, bloating around sternum, chest discomfort etc. Which doctor suggested to be anxiety related. Had taken antidepressants for few months, no longer taking them. Can someone suggest what the calf problem looks like and what should I do?
