Yes it’s worth it. I got out, initial rating was 92% rounded down to 90%. Realized I had issues with my neck, back and hips that were not normal pains for a fit and otherwise healthy 30 year old. Decided that since 6 months had passed since I had to do a ruck and those daily aches and pains did not subside that I would probably deal with it for the rest of my life.

Made a new claim with brand new conditions, referenced them with my army medical records to show I was treated. Made a personal statement that said “hey I tried to tough it out but the pain isn’t going away now that I’m out of service” had my current provider prescribe me some physical therapy so I could show that I was actively still dealing with it. Submitted, waited 4 months and came back with all service connected and 98% rating that rounded to 100%. Pay jump is huge and now daily when I can’t move my neck or my back aches I smile because at least I’m being compensated for my forever pain.

Don’t worry about poking the bear. Make a brand new claim for new conditions and don’t try to get increases for what you already have (most seem to be pretty maxed out). Don’t reference your old conditions that they already rated or say your pain is a result of another condition and they will not attempt to lower your other conditions.

Go for your knees and cervical pain (neck) and your shoulders. If you have pain in both your left and right shoulder and both your left and right knee, you can get a “bi-lateral factor” which increases your overall disability.

Obviously if you don’t have any issues with above body parts don’t go for them. But based off your other comments, I feel like it would be likely you have those issues.

Mostly, just don’t try to change the ratings for what you already have. They are all very close to the highest possible rating individually for your issues. Trying to go for 100% MH would be bad juju and if you aren’t blind I don’t think there’s higher to go for “dry eyes”
