After the rash stage, Rocky Mountain spotted fever gradually starts to retard the neurological system and eventually causes deafness, cranial neuropathies, spasticity, paralysis and photophobia. It is all about how prescribed medicines such as antibiotics and analgesics work to accelerate the process of recovery. If the treatment succeeds, the patient can recover within a week.
