[|Human|] I have had for 2 days sharp pain in my forearm area, 3/4 up my arm, in the tendon muscle area, when I push in that area sensitive -- no idea why, sharp acute pain comes out of nowhere - also knuckles hurt and wakes me up - 62 yrs old, excellent shape, good over all health, but that same hand s thumb is arthritic so it might be connected?
[|AI|]  Hello, Cannot say in your particular case, but generally, localizing pain to what is painful is the first step. A classic way to differentiate heart from muscle pain is if the muscles are sore to touch or movement then not the heart.  We generally are NOT aware of stresses that cause pain later on in tendons and joints. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
