Off late on my both solders i am suffering severe pain and enable to make any movement, i feel like inner vain of my both hands are getting stretched/pulled (right from my solder to the finger tips and swelling on both hands and legs are still there. My doctor says that it may continue for another two three months and proscribed me only pain killer tablets.Doctor says that there is no specific medicine for Dengue. I got thorough blood and urine test along with other test like scanning, x-ray etc. All the test reports are normal except slightly blood sugar (PP) on higher side and enlargement of prostate gland (which is there since last 10 years and i am on regular medicine (silodosin 8-mg, one tab a day) Kindly advise me with your good suggestions that what could be the cause of this problem and which expert doctor I should consult since it is very difficult situation for carrying out my routine activities and also I can't sleep properly due to severe pain.
