Hi. Thanks for your query. Noted the history of unexplained weight loss, in spite of eating normal, bruising on legs, very sensitive legs and toes felling like sunburns but not actually present, pass BM once in a week, under stress, gets very cold... All this history is indicative of a generalized disease may be like diabetes or so. I would advise you the following: Consult your PCP or GP for clinical evaluation, examination, investigations like that of blood: CBC, sugar, HbA1c, thyroid, liver and kidney functions. Once get diagnosed, get a reference for a specialist, get the disease thus detected. Additional treatment with supportive and symptomatic medicines need to be started to get the relief. Once the basic cause is found, this too need a proper management.
