Would I recieive backdated payment when I submit my PIP review ?

When I submittted my PIP form in 2022 I scored 0 points for drop foot on my rt foot as this was vey recent less than 3 months.My drop foot lasted about a year on my rt foot. I have now been asked to do a pip review form for 2025 , when I reiceved the form I had to ask for extra time as Iwas in hospital for over 3 weeks,as bothmy right foot devoped foot drop again and my left fooot developedfoot drop, i literay walk up with this and had to be wheeled into the hospital in july 2025 as I was unabel to walk, My right foor began ableto mveagain so i was abe to use my right foot ( foot that I had previous foor drop on ) but i was unable tomove my left foot , Neurologist gave me some tests and after 3 weeks of being in hospital , they organised more tests and a nerve bisy but there is a waiting list for these things,so I was discharged, the physiotherrpais gave me some elbow crutchesas I was not able to balance using a walking stick, they also gave me a zimmer/ waking frame to use and a boxia strapfor my foot it is mmeant to keep myfoot up but I have troube utting it on on my own and when I use it I find it painful, it hurts my calf muscles and it maes me foot hurt even more , Iam in a lot of pain and have gappentin, paracetomol and codeine to ease the pain, I am not able to walk 20 metres in 2025. but I may scre 0 points asI have not had this for longer than 3 months. I had thesame issuesin 2022 which I did not challange. I had foot drop for almost a year in 2022 , if I mentiond this in my form will the asessor back date this? also does the asessor have the authority to back date this,so I willhave about 8 months backdated of highrate mobility for 2025 andabout 3 months lower rate when i was able to begin to start walking again. I heard it takes months for the assesors to start lookingat t the claim, if it takes them 4 monts tlook at mine that would they grant me higher ratemobility because i cannot walk 20 metres ? Neither myself of the neurologist know exactly what is cauding the foot drop. it is making my mental health worse, I am also inn a lot of pain I have to take pain meds which make me drowsy ot affects other parts of my life. it seemsunfair that just becase both in 2022 and 2025 the foot drop happened just as I was starting my review forms, wherethey ask for a problem to have lasted 3 months. while in 2022my foot drop was on my right foot andin 2025it was inmy left footandsince 2022 i still have neuropahicissues with my right foot I see a podaitrist private who confirms the issue I have wth my feet butsheis not a nuerologist . my question is, if i mention on the fprm that my foot dtop issues startedin 2022 and it took me about 9 or 10 months to walk without aids for morethan 20 metres, willtheyback date my pay tp higheraward pip. woth my 2025 left foot willthey put me on ighrate monility because i cannot walk 20 metreswith aids since july 2025. my foot drop started im 2022 on my rght foot, that got better eventully now my left foot is affected, i am on strong painmeds ad waiting for more tests, will they give me high rate mobility as I cannot walk 20 metres, and although on 2022 it was my rightfoot, istill haveissues withmy right foot, although I managed to walk eventally wothmy RT foot, now my LF foot is unabletomove srely this classes as the same problem, thereis a nurological issue with myfeet. are they likely to back date the time I had issues in 2022 nd will they give me high rate mobility in 2025. my form hasto be in soon. I am due to go into hospital with my kidneys and I have asked for an extension twice so I must get this in.I would welcomeany advice.

Thank you so much, I will alter tje woording ony pip 2025 for,m so I make it clear that my drop foot started in2025 and I had it in both feet in July 25 and now I cannot movve left foot in 25 and am in a lot of pain, awaiting furhter tests and yes I will explain that unless they are willing to hold out there hand so i can take it andout my hand on my back ( like the nurses did if they needed to assist me to commode etc, then I will not risj falling) I will be sure to explain that my foot drop which is a nurological issue started in 2022, so hopefully they look at my mobility claim from 2022, as far as my personal care I got that for emntal health, my MH has declined sincce due mobility, pain and isolation and i need someone in the bathroom with me to help me was h my hair and get out of the bath safely as I do not have a walk in shower etc . Thank you for this, i did not know there was a time line , but no use fretting about that now. I really do have to taxi everywhere and there are other expnses such as a walkeras the crutches are too unsteady and I struggle in the kitchen and shops, so I do need extra money as like everyone else my other pip money is going towards things like keeing the electric bill on. but thank you, I have my pip answers saved on word andi will change it to reflect that I have been sffering from foot drop since 2022, i will have tp say that I was able to move my foot after about ayear but still had neuropathic issues, then I will say in juy both right foot and left foot stopped workinf so I hd to be admitted now my left foot will not move and is in pain while my right foot cn still move but i can feel neuropathy and visit a privte podarist. - Canyou tell me as this is the FIRST time in over 20 years I will be claiming for mobility instead of care is it likely I will have to see an asessor or will they do it all on paper, I have not seen an assessor for over 20 years? and will they just focus on mobility? or care and mobility? thanks
