hi my name is denise I am having extreme heaviness in the body and legs along with weakness, lightheadness and finding it a little bit difficult to breath. I have been to my doctor on monday and she said could be kidney infection??? but I have no symptoms of kidney infection?.  I had something like this about 1.5year ago just extreme heaviness of the legs which lasted nearly six months, again had a lot of tests done and nothing showed up. I am very fustrated with this I am on no medication, and I can not seem to get any answers as to why I am having these problems.
Hi friend, Welcome to Chat Doctor You will benefit by consulting an Internist / get examined; get investigated.... Simple tests can exclude kidney problem...no need to guess! The description suggests likely Thyroid deficiency or Depression.  Hormone assays, blood counts and so on are necessaryPsychiatric assessment may give clues.../ Consulting a heart specialist does not mean - one has heart disease; similarly, a psychiatric consultation can exclude masked depression, if any...
