Thanks for the query to H.C.M. Forum.
Swelling all over body ( more or less), numbness
, effected by heat and cold , tingling
,weakness, dull pain from last 10 months .
Since , you have not mentioned the age, gender , blood reports, so without these it is very difficult to evaluate the disease.
In my opinion may be due to ,
hypoproteinaemia,chronic renal failure
congestive heart failure
THYROID IMPAIRMENT ,Diabetes
Consult a physician and get his opinion and get all above mentioned test.
Hope I have answered your question.
If further any question I will reply.
