I am experiencing earache since last one month. First it seemed that it is a toothache but with time now it is confirmed that it is earache. Due to it my gums are also swollen and I am also experiencing headache. Currently I am taking five phos,calc.sulph,nat.sulph,nat.mur,silicea,calc.flour and kali mur tablets in 200x potency. Whenever I feel pain I take those above all the medicine and immediately pain subsidies. I want to know are these above biochemic medicines are safe? I have to take it 4-5 times in 24 hours. Can I take it long term? I have a history of mouth ulcer and sinusitis.
