Took 2 500 mg of Tylenol and am drinking lots of water thought those two things would help also using heating pad with no relief. What do I do now . In severe pain especially the arms [/INST] Hello, The pain in the arm seems to be related to the over the use of the muscle. I suggest using anti-inflammatory medications such as Acetaminophen. I also suggest using anti-inflammatory cream for local application such as Voltaren cream. Hope I have answered your query. Let me know if I can assist you further.
