The Veteran's service connection claims for psoriasis and psoriatic arthritis were granted. Psoriasis was presumed to have been incurred in service, while psoriatic arthritis manifested within one year of separation from active duty.

The appeal for service connection for fibromyalgia was granted with an effective date of August 14, 2023. The appeals for earlier effective dates and higher ratings were denied.

The Board denied service connection for multiple conditions, including rheumatoid arthritis, right hip degenerative joint disease and rheumatoid arthritis with acetabular cyst status post right total hip replacement, osteoarthritis, psoriatic arthritis, hypertension, prostate cancer, diabetes mellitus type II, fever sores, and a compromised immune system, as the evidence did not support a finding of service connection for any of these conditions.

The Board remands the claims for service connection for multiple conditions due to a need for additional development, including obtaining medical opinions considering all toxic exposure risk activities (TERAs) under the Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxins Act of 2022.

The Board remands the claim for a new examination to more accurately assess the severity of the Veteran's psoriasis, as the previous assessment did not consider all areas affected and recent photographs.
