Hi
Welcome to the MedHelp forum!
The first thing that you need to do is consult an ophthalmologist. The problem could be a foreign body or glaucoma or any inflammation. It can also be an inflammation of nerve. It could also be poor eye sight as in near or far sightedness.
Since you have a neck and shoulder pain too, possibility of pinched cervical nerve, trigeminal neuralgia, temporal arteritis, benign intracranial hypertension, hypothyroidism or diabetes causing neuropathy etc too should be looked at. I think you should discuss these possibilities with your doctor and get a referral for an ophthalmologist and a neurologist. Hope this helps. Take care!
Sounds like cluster headace. The one side of the face the sharp pain in the eye. I'm not an expert but that's what I found when I searched up how I've been feeling latly
i would tell see the new doctor which take interest in you for the pain bcoz having pain on the left side of the hand shoulder is not normal it can be related to some heart prob im not sure but as much i know i can tell you go see the doctor ASAP a good doctor .
