Suggest Remedy For Severe Headaches When Suffering From Glaucoma

I have glaucoma. I know my right eye I can now see Like smoke of waves rising all the time have terrible headaches I do have a un treated Broken head the humerous( right shoulder ) which happened in 2011 agony, due to kayack accident , the medical insuran ce company repudiated the claim. I add this on as my historical health factors could be worn down motors !!!! I have had ops on my c4 spine , Maleria 8.5% blood, have had to return to the Uk as cannot work due to this ridiculous situation. I have spent my entire life paying for private medical care , and am very aware that the NHS is very very understressed financially. I have been given tramadol for the pain , cocodamal, I take fluxatine 40 mg 6 mg diazapan timitol eye drops 2 times a day ( last check temp) 16- 18 ( was caught late in usa at 34-28 pressure...) 2 mg melatonin at night (try to not lose my short time memory) I am 62 ( strong normally) I do have Ptsd from Africa , but something is not right. I go to Drs here but they do n t even do a blood test due to the NHS which is so brilliant but so underfunded I have to wait 46 weeks for appointment with orthapedic surgeon ,whom I know will want to do a shoulder replacement , but in the meantime what on earth shall I do? I think this is all neurological due to shoulder , ????
