Hello,
I can understand your concern. There can be two possibilities in your husband's physical condition. First is, he might be having some heart problem which may cause pain in left arm and jaw. You might not feel it serious enough for now but it may increase in intensity and may cause emergency later. Thus, it is better to get it checked once by a cardiologist by an ECG.
In absence of heart problem, the
hand cramps and jaw pain will be different entities to treat and just a co-incidence that they started together. I would advise you to gen at an appointment of a
dentist to check for presence of an infected tooth and abscess related to it. If that is the case, then after getting treatment of that infected tooth by
root canal treatment or extraction depending on the extent of infection, your husband will be pain-free. The hand pain might be related to the
muscle fatigue due to yard work and can be relieved by taking mucle relaxant medicines like Dan-MR (
Paracetamol 500 mg +
Diclofenac Sodium 50 mg +
Chlorzoxazone 250 mg) twice a day for 5 days. In addition to that, compression heat and local application with Diclofenac Gel (Volini) will help.
I hope this information helps you. Thank you for choosing HealthcareMagic. Let me know if you have follow up questions.
Best,
