<s>[INST] I have had pain and swelling for 9+ days. The x-ray didn t show an infection in the tooth but that is how they are treating me. The meds are not helping but I find that putting water in my mouth relieves some of the pain. It feels like my mouth tightens and releases similiar to a contraction. I am at my wits end with the pain and lack of sleep. [/INST] Than k you for your query,The symptoms which you have written are suggestive of muscular involvement around the jaws joints.You can start muscular relaxant along with analgesic, this combination will give you relief from your symptoms.I case it does not, then we have to go in for more comprehensive checkup. </s>
