Hello, Thanks for choosing health care magic for posting your query. I have gone through your question in detail and I can understand what you are going through. From the medications that you have stated it appears that the treating doctor is not sure about the cause of his neck pain. Reason could be an unreliable history. Yes the medications which have been given are of different groups and may not interact much with each other except for reducing the BP which needs to be monitored. Otherwise its OK to give these medications in the dosages mentioned. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you. In future if you wish to contact me directly, you can use the below mentioned link: bit.ly/dr-srikanth-reddy Wish you good health, Kind regards Dr. Srikanth Reddy M.D.
