Hello,
I have gone through your question and understand your concern. As you have mentioned the blood test and stool test came negative for parasites,you can be assured that it is not the parasite that is causing you severe back pain.
In my opinion, firstly you need to see a GP for your back pain as chiropractor and acupuncture will help you only with the symptoms and will not help you with finding the root cause of pain. As you have mentioned about no insurance and only medicare at your hand, GP is the best option in your case. No expensive specialist or diagnostic test is need other than x-ray and then pain relief medication will be provided only after checking your x-ray and a detail physical examination.
Secondly, the hair fall could be due to anything from advancing age, poor diet, low blood levels, thyroid disorder. Regardless of cause a balanced diet will help you with the issue, add a whole egg to your diet as it contain biotin and a single daily dose of multivitamin like Centrum. Do not expect quick results as it may take a few months to replenish the nutrient stores of body.
Lastly, the complain of Morgellons and cloudy mind with breathing difficulty can be helped only by your own effort. Morgellons is a delusional parasitosis, which could have started due to your occupation which involved being in close proximity of animals. Just be assured that you have no parasite living inside or upon you. Convey it to your mind and body that you are free from parasite. That itself will take care your issue without spending time or money at a psychiatrist for behavioral therapy or medications. In case of no improvement seeing a psychiatrist will be of great help.
