I've been having cold since 15 days. But, now, here since last 3 days, after waking up in the morning.. I face a severe headache and extreme weakness in my body. My lips and throat are getting very dry. I'm facing difficulty in breathing due to cough. Yesterday, I had visited a Doctor. He checked my BP and said I am having low BP (90/120) & suggested me to eat a lot and drink juice and plenty of water. After drinking plenty of water at the interval of every 30 mins. I was fine last night. But now in the morning, I'm facing it all over again. Also, I have lost my 2 kg weight in last 2 days. Please suggest some permanent solution.
