Hello, Welcome, and thanks for sharing your concern I went through your query, and I feel, its not rational to develop the habit of drug dependence, if there is any structural or physiological cause of your pain than tests these days are sensitive enough to detect them, but if tests are normal, than pain is more psychological, and this need determination on your part to get rid of the drug. If you are weak and dependent, than you will need this drug forever and then the side effects will have secondary problems for which your weak mind will need even more medicines. Its better not to develop dependence, and do regular yoga and exercises to boost your moral, and reduce your dependence on drugs. I hope my advice would have been useful, in decision making regarding your treatment, still if you have any clarifications or doubts feel free to contact back. Thanks.
