<s>[INST] I have what feels like a very sore and bruised 2nd metatarsal on the right foot and painful to walk on it.  To the touch the area on the right foot feels like a hard lump and swollen compared to the left foot which is not swollen and no lump like hardness under the fleshy area.  I normally wear MBT rockers due to ples planus.  I am a teacher and on my feet most of the day.  Tonight it even hurts elevated.  Will heat or ice help? [/INST] Hi, DEar, I went through details of your query to Chat Doctor, thanks for it. In my opinion rt foot swelling is due to the mismatched MBT-rockers for the PES plans. You need to get the proper MBT shoes-from the gender, from whom you bought it. I would advise taking anti-inflammatory tbs from your doctor and take orthopedic opinion -if the problem persists. Hope your query is answered. Wellcome again. </s>
