I have few remedies here for you here but it is advisable to seek professional medical help before using them.
Sniff an onion. "Basically, the only thing you get from rubbing on menthol or other decongestants is some irritation that stimulates the nose to run and unblock the stuffiness," says Venice, Florida, otolaryngologist Hueston C. King, M.D., visiting professor at the University of Texas Southwestern Medical Center at Dallas. "You can get the same effect from smelling an onion."
Go heavy on the spice. The cure for a stuffy nose is to make it runny, and few things make it run faster than spicy meals. "Hot and spicy foods trigger a reflex response to make your nose runny," says Gordon Raphael, M.D., an allergist and a former researcher at the National Institute of Allergy and Infectious Diseases in Bethesda, Maryland. "Eat some hot chili peppers and your nose will immediately start running." This running helps break up congestion and remove irritants that may be causing the stuffiness, adds Dr. King.
Treat it with zinc. "Zinc seems to have a specific effect on the nose," says Dr. Chester. Zinc supplements have been used to treat people whose sense of smell has diminished, and zinc may improve congested sinuses as well. Take a 50-milligram supplement daily, Dr. Chester suggests. Continue to take the supplement if you notice an improvement.
Or my best remedy for colds and pain realiving is 'Nutmeg'.
We use Nutmeg powder for commons colds and pains, for colds we make a warm paste (with little water and add nutmeg powder to form a paste) and apply it to your nose and forehead before you go to sleep at night ensure that it's not to hot and just warm, it's pleasent and it dries out within few miuntes, in the morning you can wash it off, do this couple of nights and inshallah you will feel better normally for me one application is ok it gets rid of colds and it works if you have blocked nose too.
For aches and pains, i use to suffer from 'Tennis Elbow' Which is a form of pain in the elbow joint section, but mashallah i applied the Nutmeg paste as above onto the affected area for few nights and it got better altogehter with taking any harsh pain killers.
Now 'Nutmeg Powder' is always in our kitchen cupboard, it does not have any side affects.
Hope it helps inshallah.
