The Board denied service connection for a psychiatric disorder, to include PTSD and an upper respiratory disorder due to lack of evidence linking these conditions to the Veteran's military service.

The Veteran's claim for service connection for degenerative arthritis is denied as there is no evidence of a current disability and the STRs do not show any treatment or complaints related to this condition.,Service connection for myocardial infarction is denied because there is no indication that it occurred during active duty, reserve duty, or within one year post-service. The Veteran's STRs are silent on heart problems, and his current diagnosis of a myocardial infarction is not linked to service.,The claim for service connection for PTSD is denied as the Veteran did not have any in-service stressors that were verified by VA and there is no evidence linking his current psychiatric condition to service. The STRs do not show any treatment or diagnoses related to a psychiatric disability.,Service connection for hypertension is denied because there is no indication of hypertension during active duty, and post-service records are negative for this condition. There is also no link between the Veteran's current diagnosis of hypertension and his military service.,The claim for low back disability is remanded as the VA examiner did not consider the Veteran's STRs showing a motor vehicle accident in service that resulted in back pain, nor did they perform any diagnostic testing.,Service connection for right knee patellofemoral pain syndrome is denied because there are no STRs indicating treatment or complaints related to this condition during active duty. The VA examiner also noted the absence of contemporaneous medical records showing evaluation or treatment for the claimed conditions.,Service connection for left knee patellofemoral pain syndrome is denied for similar reasons as right knee, with no STRs indicating treatment or complaints related to this condition during active duty and no diagnostic testing performed by the VA examiner.

The Board has denied service connection for various conditions, including right hip, left knee, and right ear disorders (other than hearing loss or tinnitus), as well as sinusitis and an upper respiratory disorder. The Veteran's symptoms have been attributed to his already service-connected allergic rhinitis.

The Veteran's service-connected PTSD is granted, and the Board finds that his current psychiatric disorder is related to in-service events. The issues of bilateral hearing loss, GERD, diabetes, left knee disability, asthma, allergic rhinitis, and hypertension are remanded for further development.

The Veteran's claims for service connection for OSA, CFS, fibromyalgia, IBS, and GERD have been denied as there is no evidence of a diagnosed disability or link to service.,The Veteran's claims for service connection for urticaria (claimed as chronic hives) and an upper respiratory disorder are remanded due to the need for further medical evaluation.
