I was on esa til after failed medical and lost my appeal aswell so had to go on universal credit

Were you refused PIP or ESA? If your condition worsens you can get medical evidence and send it to DWP. Did you just get a mandatory reconsideration or a hearing at a Tribunal?
I got PIP for daily living, I sent in more evidence, and after an ATOS medical I was upgraded to the full allowance with mobility.
I had a medical with Maximus for ESA which was a farce. The doctor gave me zero points despite the fact that I got maximum points for PIP. I was refused at the mandatory reconsideration, but have my Tribunal hearing in August.

HI Steph. I'm assuming you were on ESA. Since it's now more than 6 months since your "medical" you can go back to your GP, ask him/her to sign you off as sick again, and you can re-apply for ESA on the grounds that your symptoms have gotten worse due to the stress, which I'm sure it has. Make sure you keep a copy of every certificate you send to DWP. You can also make a claim for PIP. You have nothing to lose by trying. Good luck and gentle hugs.

I claim pip only for daily living allowance and didint think u cud reclaim if for same condition

I had to go to a Rheumatology dr to be checked out for fibro. Sorry I wasn't declared disabled for fibro till after diagnosed with chronic heart failure and bronchial asthma..
