i get water up my nose when washing my hair (i hang my head upside down under the tub faucet) & the last time this happened (few days after) I began sneezing coughing horrible headache and sore throat. I ended up getting medicine from my mom who is a nurse but I dont think she has anymore and  I think this is happening again I dont want to call off work to go to the doctors.. What low cost medicine could I take? or home remedies?
First try to follow NIDAANPARIVARJAN (in Sanskrit language) that literally means avoidance of course. When you know the cause of sneezing etc., do not try to repeat off and on. However proven home remedies are leaves of Holy basil, ginger pieces, one pepper black may be boiled in water for some time and sip it when temp. Comes down to warm. May mix it in 2 tsp honey. If anything of above is missing, go ahead with rest. Better take 1/4 to 1/2 tsp turmeric powder twice a day with it or with plain water. Steam inhalation may be taken at night. If you need more information and simple natural remedies for other problems, pl write direct question.
