Also wanted to add - when people have non-pregnancy lymphoedema, they can get a lot of relief from being in water (eg in a pool or in a warm not hot deep bath). It works because the pressure of the water helps push the fluid back into the lymph drainage nodes. You could ask your dr/midwife whether this is something that would be helpful to make you more comfortable right now. Some hospitals have a hydrotherapy pool that is available for use by pregnant women, worth asking about if the dr agrees it could help.
